I love my 2200. It is silky smooth and the dust collection is awesome. As other posters have noted, it needs to be well supported because of its weight. As examples, I've used mine for cutting large (2'-4' diameter) circles for frames and with the Festool MFS and Woodpeckers variable router jigs. An example of an application where I think neither the 611 or the 2200 is a good match is cutting dovetails with a Leigh or DeWalt dovetail jig, as a lighter router is a bit under-powered and lacks support, and there is a higher risk of slightly tipping a heavy router over the edge of the jig.
In choosing between the 1100 and 1400, I finally settled on the 1400 because it comes with a 1/2" collet. Since you currently have a 611, that's probably not a big deal for you, but a 1/2" shank is almost a necessity for larger diameter (1" or greater) bits. I've seen at least two larger diameter 1/4" shank bits break in my life. Both times the router was in a table and the head of the bit came out the bottom of the table and did not cause any injury, but did ruin the cut. Once a shank is torqued out of round by over-stressing it in a cut, it doesn't take long to beat itself into breaking. The only 1/2" shank bit that I have ever seen break was a dovetail bit that broke at its narrowest point. I use 1/2" shank bits whenever possible. I only use my trim routers for lightweight tasks that don't put a lot of stress on the bits - chamfering, laminate or other light trimming jobs, light dadoing, inlay, hinge mortising, and so on. I think I only have one 1/4" bit with a diameter of more than 3/4", a Whiteside 45 degree chamfering bit with a guide bearing, and I never use the full size of that bit. So if you see yourself also using larger bits, take that into account when picking a router. I feel more comfortable using the 1400 with a dovetail jig because I can use 1/2" bits.
