Speaking of shedding, we have a bearded dragon named Gizzard the Lizard. He's a riot. They do get a little cranky when they shed their skin 'cause they're all itchy, but they aren't much more maintenance than Bob the Beta Fish (our fish). Plus beardies are quite easy-going and you can take them out, put them on your shoulder and have a buddy hang out with you all day.
Beardies seem to have so much personality that they are really fun to own. They live to be about 8 years old, but can live as long as 12 years and get up to 2 feet long. Here's a good site on beardies if you are interested.
