Hi
I just bought the PSX1103012/professional because it's large enough for any pot/sheet or pet pot bellied pig(when was that trend?). I'm not familiar with disposals. The only advice is make sure you buy any FF sink from a Franke dealer not the much less expensive one at home destruction(HD), sorry if I'm stating the obvious. I have read where people were outraged about the quality of their sink, when everyone knows that many manufacturers are producing inferior products for the home destruction & Lowes market..

Franke and Julien makes top-of-the-line stainless sinks. So you definitely would be buying great quality BUT for the size and the price I would want a 16 gauge sink (thicker) and one that's deep -- 10 inches is nice (though depth is simply preference) which helps with splashing.

I'd also look at Julien sinks which have many options. I bought one online -- they are basically to order and there can be a wait but it was worth it.
