not to beat a dead horse, but i keep veileds and they've never been a problem. they're from a desert region actually so the humidity and temp requirements are extremely easy to hit. we just keep ours in large screen cages (i posted pics a couple months ago in the caging forum) with a reptisun 10.0 for UVB and a 120w bulb for heat. they're probably the most 'interesting' herp i have.
oh yeah, and we got a pair for like $45 from a local breeder.
