..... I have a junker table saw, ....
So, my question is: to build my own kitchen cabinets, as a newbie, what tool(s) would you guys recommend? I want to be able to say to the wifey "look, we can spend X on cabinets from a manufacturer, or I can make them for Y, even if I spend all this money on tools"...
Bad tools suck sawdust

. You waste material, time and get so frustrated the extra 0 suddenly won't look so bad.
I'd recommend the TS55 saw with it's rail for cutting your plywood. I'm using it to breakdown the plywood for my kitchen cabinets and it's fantastic. I also used the guiderail with my DeWalt router to make dados in the side of the pantry.
If you want to save some cash, I'd avoid buying some Festools, like the router, drills and Domino. The domino is very expensive and not really necessary (I don't own one) and other, less expensive routers and drills can get the job done very well. That stuff does resell very well on ebay.
I say to those who will chastise me for my comments on the Domino, we were doing this kind of work long before the $Domino$ came around, it's not necessary to spend that kind of money on one tool.
The MFS table may or may not be a good option for you, but I'd skip the angle attachments as it's well know they are not accurate or repeatable. (Boy has THIS horse been beaten to death!) It has been offered by some that the MFS is a good assembly table (like putting drawers together) and I'd bet it is, you can buy a bunch of good clamping options for it or make your own jigs. Again, it's expensive but maybe a good option for you.
A good, quality bench saw will be awesome for cutting drawer parts. It can't be beat for repetative rips, like drawer parts and face frames. If you buy a dado set you can cut dados and rabets, but those can also be done with a router.
Get a nice sliding collum miter saw for cross cuts, trim and crown molding. I have an older DeWalt but some members have praised their Makitas, I'm not sure of the model. I'd urge you not to buy the Festool Kapex $1,300 is a bit much for one kitchen, save your money for other things.
I've used the Kreg pocket hole jig to join my face frames, wow what a joy it is to use. I originally had the big jig, but sold it and bought the Kreg R3 ($39.00) after using a friends. My special ed kids use it here at school, it's that easy, a a lot cheaper than the Domino.
I have the ETS 125 and it's a joy to use. I purchased a drywall bag and HEPA cartridge filter for my big shopvac and I can sand indoors with no signs of dust.
Also check out McFeely's, they are a great resource for fasteners and tools, plus there are several good Festool dealers regularly online.
My kitchen was priced at $36,000+ by a cabinet shop without counter tops and me installing it. I can build it for less than $4000 in materials ( I already have most of the tools). A good friend does my granite counter tops for his labor only.
A kitchen is a big project, probably not exactly beginner material but you may have the inherent skills anyway (some people are born that way). I'm 3rd generation carpenter, worked in construction and teach woodshop, but you may be more capable than I am.
If you are not familiar with the use of any of these tools I'd urge you to get some good instruction on their use by someone who knows. Also get and use a good pair of safety glasses and use the machine guards.
If an IKEA is near you, you might look at their cabinets.
