+1 on the cresties; the only thing about them that's even slightly hard is humidity - they need it to get moist at least some of the day, every day. Unless your house is super dry, they only need to be misted once a day in my experience. The powdered diet that's available for them makes feeding super easy (and cheap). A decent sized vertical terrarium and an automatic misting system and they're *almost* maintenance free. Just have to feed every couple of days and clean up after them reasonably regularly and they're happy, plus most of them are pretty darn tolerant of handling, if you're so inclined.

As WWPsion said, however, if your house's temps exceed 80 F by more than a degree or two, they don't fare well. Short (minutes, not hours) exposures of 82 or 83 can be tolerated, but they should NEVER be above that.
