Sous Chef 9

Most food processors will do slicing (with varying degrees of adjustability), and there are also food processors these days that dice. They're not cheap (for instance, the Breville Sous Chef starts at about $500 new), but they're effective and mostly effortless. Lack of a dishwasher would make clean-up harder, though. As with most forms of cutting up vegetables and such, you'd still need to remove any ends and bits you didn't want in the final product. I umpteenth recommendations for cut-proof gloves.

If it makes you feel any better, I busted a few parts on my Breville Sous Chef using it to make pizza dough. And that's one of the higher end non commerical food processors. It was my fault for letting it run to long, but it wasn't like I ran it an extra 2 minutes, it might have been 25 seconds longer than I meant. I was able to order replacement parts, but if that food processor struggled, you're gonna have to get a Robo Coup or something high end for one that won't bog down too much. You don't do longer kneeds with a food processor, I think even with something like the Sous Chef the recommendations I came across said don't run it longer than 60 seconds. When I used it properly, the dough came out really great with very little kneed time. If you're set on using one, you should check FB Marketplace & Offerup for used Sous Chef, they're built like tanks. And can be found used for pretty good deals. Also, Breville includes a 20 year warranty on the motor.

Second the Magimix. By far the best I've had, and I've owned a lot of them (they didn't last long). I never thought I was being terribly demanding; I just wanted one that was durable. I even went through a Breville sous chef in just a couple of years--parts kept breaking, motor strained, etc.

I have been through a few. A few years ago I splurged on a Breville Sous Chef with peel and dice, and finally found a food processor worth getting out of the cabinet. You’re welcome.

Breville Sous Chef. Built like a tank.

I've used a Breville Sous Chef food processor and a Vitamix 6200 blender to make nut butter. The Vitamix is a lot faster and produces smoother nut butter. So I guess it depends on the blender but I would say a powerful blender like a Vitamix or Blendtec is better than a food processor for making nut butter.

If you can get a used Robot Coupe that would probably last longer than any other brand. I have a Breville Sous Chef and I like it for personal use.
