I bought my first food processor in 1978, Cuisinart, and used it (a lot and regularly) until last Christmas, which is when Glenn gave me a brand new one as my big Santa gift. This means my trusty old machine was 35 years old when it went to live with another family.
There was nothing wrong the my old one but I wanted a little more versatility and the new one definitely offers that. There are three prep bowls in graduating sizes, along with all the cutting blades.
I have never had any issues with my Cuisinart machines and am just as happy with my new one as I was with the first one.
I highly recommend Cuisinart. I chose the 14-cup Elite model in die cast because I wanted something durable and of ample capacity. Here's an Amazon link
to what I have.
