Hamsters are the best. I had several growing up. They're personable - you can "cage-train" them and they learn not to bite. They're hilarious when they roll around in their ball -- and remember to cover your stairs! They do the cutest thing with stuffing food into their cheeks. You can easily build elaborate living environments for them using cheap tubing. You do have to change their cage at least once a week, but it's easy - dump it out and pour in new mulch. Think of the cheeks.
