Sorry to contradict all those of you who say beardies are boring. You obviously ain't doing it right. My son has two, one male, one female and they are both lively as you like. They are got out and handled daily, put on laminate floor and do the silly cartoon run (all action, no motion). They sh!t once a week, though it is a pile, eat 15/20 adult locust or 40ish adult crickets (food bought in bulk isn't so dear) as well as plenty of fruit and veg (no salad, gives them the runs). We don't breed them, far too many beardies on the market but it's a doddle if you want to. The set up cost us about 80 quid though I built the viv myself (it's a 4x2x2, materials cost 30 quid). A bag of kiln dried sand on the viv floor, 4 quid a year, does a good job and makes cleaning easy.
My advice, go for it, beardies are like any other pet. You get out of them what you put in.
