I highly recommend the Cuisinart 14-cup Food Processor.

You can find them used for $100-$300. I think the new ones are probably be fine, but it might be safer to get one manufacturered before 2021, when Cuisinart was bought by Conair. And probably avoid the ones with riveted blades, since in 2016 there was an issue where the blades broke apart, and people were injured by eating small pieces of metal.
The smaller 3-cup one is decent, but I broke it making peanut butter. It's really not designed for that kind of abuse. So I wouldn't recommend it.
But these 14-cup ones are tanks that will last generations. You can buy replacement parts. And there's loads of used ones, so you should be able to get spare parts for generations.
