Cuisinart - Smart Power Duet Blender/Food Processor BFP-703BC

There is a well known, well regarded, kitchen appliance company (Cuisinart, since everyone else is naming names) that makes a 2 in 1; it's a common base with a food processor top and a blender top. I used one for years, still have it, and it works great. You might try one of those so you don't have to choose. It's usually available for about $100 on Black Friday sales.

What do you use a food processor for? 90% of my usage is for 2 things. Salsa and chopped nuts (for pad thai or baklava). I have the smallest 3 cup Cuisinart. For my salsa recipe it does require doing 2 batches, or baklava nuts needs multiple batches. I can't recall a situation where I wished for a bigger food processor. But, I also don't have situations where I am debating "I have to get the food processor out or I can do it by hand." I just grab the food processor. I will add per another commenter I do have a stand mixer, so I am not trying to use a food processor in situations where the stand mixer is better.

I have a Cuisinart 3 cup that is basically the same as your KitchenAid. I got it off Amazon for $20 but the price has since increased unfortunately.
