Cuisinart!
Cook's Illustrated rates the Cuisinart (Model
FP-14BCNY 14-Cup Food Processor) as their top pick. It's about $160 on Amazon. It's what I have and it's fabulous. It comes with the standard s-shaped blade plus a grating disc and a slicer disc. You can buy more types of discs and blades if you need them, but I hardly use anything but the standard blade. I bought it to replace a 10 year old discontinued KitchenAid that I had previously loved but worked
to death. This one gets used multiple times per week. (The blades stay sharper if you hand wash, btw.)
The Breville Sous Chef 12-cup food processor is rated after the Cuisinart, then a Black and Decker Performance Food Processor. The other Cuisinarts (smaller models) are all Recommended With Reservations. CI doesn't rate the new Kitchen Aid very highly despite it's new technology - it's in the Not Recommended line up along with Oster and Hamilton Beach.
