Tom,
I have been a hobbyist and DIY remodeler for >30 years, trained by reading and making my own mistakes - lots of them. I have 5 routers. In order from oldest to newest they are:
1) Craftsman 1/4" fixed base 6.5A with nice pistol grips. It's currently mounted in a poor man's table - an old birch veneer pine core plywood cupboard door. I used it with a fence made by jointing a piece of 2 x 4 and cutting out a semicircle with a hole saw to fit my shop vacuum. I used that setup to bevel all edges of >400 sq ft of 7/8"Th x random widths and lengths oak flooring I made from rough lumber. I also used it to make many raised panels using HSS bits ground to profile starting with over the counter profiles. A handy, lightweight, stable little router, but no dust collection. I also have an 8" plastic dovetail jig from Craftsman that is surprisingly versatile and works well after a little fiddling. It still runs OK but doesn't see much use.
2) Stanley 10A Industrial with fixed base and 1/4, 3/8 and 1/2" collets. (This product line and factory was later bought out by Bosch, I believe). Very well made with HD armature, switch, bearings and collets, and the edge guide and copy rings are sturdy and precise compared to Craftsman. Punished it severely cutting PVC while commercially making vacuum tanks for milking machines. Still running excellently, but again, no dust collection and it jumps from torque reaction when switched on.
3) Festool 1400. I use this one whenever I can because it is by far the quietest router I have ever used. Bought many accessories for it including the adjuster guide for use with the guide rails, hole drilling jig and hole drilling guide rail, and edge guide, 1/4, 3/8, 1/2 and 8 mm collets and several copy rings. But if Festool's 1010 could accept 1/2" shank bits, I would have bought a 1010 instead. I was torn between my large collection (read high cost of investment) of 1/2" shank bits and the smaller, lighter, sports car-like maneuverability and controllability of the 1010. I still want a 1010 that can accept 1/2" shank bits!! Although I use the 1400 for mortising door hinges, including on existing old door frames, I find its weight and relatively high center of gravity and relatively small base make it rather tippy compare to the 1010 I've played with in a store and my old Craftsman router.
4) Freud 1700 ?VPS? 13A. I bought this one a little over a year ago at a sale at Hartville Tool for ~$150 including coupon for a plunge base following direct communication with FestoolUSA's applications specialists who made it clear that Festool did not then offer any routers in USA that were designed for use in a table with or without a lift. Festool also discouraged me from removing the plunge return spring, which I still think is a bit too strong. This Freud router came with 1/4 and 1/2" collets, and dust collection nozzle that is relatively difficult and cumbersome to attach. I have never installed it yet. This Freud router is today one of my workhorses. It is installed into a JoinTech table mounted as the left side extension of my table saw which I equipped with a JoinTech SawTrain/Cabinetmaker system. This JoinTech system is much like those produced by Incra. This router can be adjusted from above or below the table, and when fully raised, the shaft is automatically locked to enable bit changes with a single wrench. I use it a lot for edging, dados and dovetails. It came with a 5 year guarantee. I think it a very good value, a lot of router for its price. It was a pain to mount accurately centered in a JoinTech router insert plate because there were no templates for it, and some of the holes in the fixed base (the one designed for use inverted in a table) are not bored all the way through. If I had to start from scratch to mount it to another insert or table, I would purchase 4 extra screws that fit the threaded mounting holes in its base, cut off the heads of those screws and point one end of each with a file, then thread them into the base, mount a centering bit, and carefully position the whole assembly on the blank to be drilled for mounting.
5) PC 7518. Long the industry standard for serious, all day long commercial work. Cost $300 plus taxes at recent Columbus, Ohio Woodworking Show exhibit. I plan to mount it in the JoinTech table extension on the other side of my table saw. I have a JoinTech lift to for it, and that lift does not fit a Milwaukee "big boy." After I get this set up with an enclosure and table reinforcements, I'll decide whether or not to keep the Freud. I considered 15A Makita, Hitachi, Triton and others before going back to the PC. I might have chosen the big Milwaukee router if it would have fit my lift and most others, but when I was looking around a couple of years ago, it did not, and the dealers I visited did not have a "big boy" in stock for me to play with. If you're planning on getting a lift, make certain that you choose a router that will be compatible with that lift.
If I was starting from scratch today, I would again choose a Festool router 1400 or 1010 due to superior quality, features and especially dust collection, and either a Freud, Triton, PC or Milwaukee for table use (assuming Festool doesn't come out with a product for this installation), and a trim router. I have been considering Bosch's Colt unit, but plan to wait to see the new Festool product which I presume will have dust collection designed in as well as other unmatched features.
If you don't already know, Freud and others now make bit sets specifically designed for making passage doors. These bits are capable of deep/long T&G cuts to provide plenty mechanical strength (M&T joints) and glue surface area. Of course, you don't have to buy one of those sets (at a cost of ~$200 per set); you can make your own jig for the mortises and then make your own loose tenons as taught by David Marks and Norm Abrams on their TV programs.
