Cresties are great and very low maintence, though I tend to view most reptiles as low maintence. I didn't buy any fancy morphs so I got two smaller ones for $40 each. I keep 2 in a 29gal tank. I feed mine dry Crested Gecko Diet (it's how they were being fed when I got them) and they don't seem to mind. I take it out before I mist nightly and that's about the extend of their feeding care. The biggest things you need to worry about is that 1.) it doesn't get to warm (above 85, though 80-85 is still a little too high) and 2.) that you don't have two males in the same tank. I would put these guys on the same level as BPs in terms of care. Other than misting nightly they don't require much care, just be careful when handling them and how you grab them. If they drop their tails they don't grow back.
