Well, the cages you're looking at come in 4 different sizes. Only the largest two (with a footprint of 18"x18") would provide enough floor space for a terrestrial gecko, like a leopard, panther, or fat-tail. If you're wanting something to handle regularly without much risk of getting bit, then that's what I'd work towards.
Most of the arboreal (tree-dwelling) geckos are pretty flighty, but there's a few that tame down fairly well. Here's my suggestions listed from easiest to tame to hardest:
crested gecko
gargoyle gecko
white-line gecko
golden gecko
Any others, like crocodile geckos, fan-foots, Bibrons & tokays, I've never had success taming down at all.
