I found with the parallel guides and a few jigs, you can build cabinets just as fast and in some cases faster then using a table saw. Especially if you are a one man show.
As far as ripping rails and styles, Tom and a few others have posted some easy to make jigs which can cut lumber to correct measurements accurately and repeatable.
Where things tend to slow down for some is during assembly. I just domino and screw the cases together. Easy Peasy, its all about work flow, have your shop drawings, cut list drawn accurately.
Remember you can gang rip ply with a track saw, including trimming the factory edge. Try that with a table saw.
Kitchen cabs are just boxes with shelves thats it nothing more or less.
Dood,ya rip the ply to width, router the groove for the back panel using 1010 and edge guide, edge band the face of the ply, LR 32 for shelf holes, finish the surfaces, set on MFT, cut to length, assemble.
I dont see a need for a table saw for the boxed.
Doors and drawers, lets discuss door, set rail on lumber, joint using track saw and rail. use kapex to cut to rough length, set on Toms shop made jig, rip to width using his jig, etc etc...
I still dont see a need for a tables saw.
Now to be honest, I do have a TS 75 CMS module, so I sort of have a tables saw. But as I described, I wouldnt need it for building a kitchen.
