For all you who cook...

I know there are some great cooks and foodies who occasionally visit...and I have a question for you. I have decided that my blender does NOT work like a food processor, and that it is time to get one. So I have made it known that this would be a great gift for Mother's day (rumor is that it is only a month away!). Normally, I don't ask for anything, my mind goes blank, except for the unattainable type of requests like, a trip to Italy (sans children) for a month. My husband does a good job remembering important dates, I'm just terrible at coming up with good ideas for myself. So, I need your help. What features, brands or size should I be looking for or NOT looking for in a food processor. I did a quick search on Google last week, and decided that although I know how to use a food processor, I really don't know if one is better than another and I turn to my friends for advice. Thanks!
