Bearded Dragons are great! I used to have two called bert and ernie! I would put pics up but cant access photobucket at work! They are really friendly too!

I also used to have an iguana... they are SO esy to look after, but obviously you'd need a bigger vivarium for them, i used to let mine wander round the house for a few hours a day, and she was potty trained! I used to half fill the bath up with warm water, and she'd go in there every day or every other day, have a swim around, then poo, then come out!!! AND she only ever ate veg!
