Should I get this crockpot for $40 at Costco?http://www.amazon.com/gp/aw/d/B001KV…

I've never had a crockpot before and I have no idea what I should get, but I know I'd like to get one. Will this be too big? I'm generally only cooking for 1-2 people, but I could just cook big batches and freeze them or eat the same thing for a week. I dunno! Help me figure out what I should do while I'm here for the next half hour.
