crockpot help

I'm looking to pick up a second hand crock pot. The problem is, I don't know what to look for to tell if it will work or suit my needs. I've never used one before. I'm feeding myself and my boyfriend, so something medium-sized so I can have left overs as well. and I want the inside "pot" to come out for easier washing. Other than that I'm clueless. what should I look for to tell that it works? What sort of dials/buttons/settings extras should I watch out for/avoid? Any brands that you would recommend/ tell me to avoid at all costs? Thanks so much!
