Just wanted to throw in a suggestion for a Nicaraguan Boa. They have a rep for being fairly nasty, but I've encountered a few real sweethearts (and a few that were fine with me holding them, but would snap at my buddy if he got close to me haha). There are some neat morphs coming out of them now. I have a friend who's going to be breeding anery and T+ albino Nics hopefully later this year, they're stunners. They stay small, but they've still got plenty of personality.
This is the T+ (apparently he's also a sunglow) that my friend has: http://www.iherp.com/Public/Animals/...AnimalID=58866
