forester is that the only thing you want out of your food processor? (the ability to make salsa and grate)
I would stay away from Cuisinart because I have seen reviews where they have quality/safety issues. The blade breaking off through the plastic and flying through the room is what I am talking about, not that great!! Not everyone has this issue but it does happen from time to time.
Kitchenaid is good.
As Andy said you want to process less. With the Cuisinart or the Kitchenaid they will have the additional parts you want that will help you do that but you must only pulse it and not over process it.
btw I wrote this article which may help you, they are the top 10 things you will need to know when getting a new food processor..

I hope this helps you!!
