i use the crested gecko cages that reptile depot makes and i love them. since they are only partially screened they hold humidity much better than all screen cages. the site is built using frames, so i can't give a direct link that includes the side menu frame but here is how to get to the page with the crested cages: go to http://www.reptiledepot.com/, click on "supplies" in the left side menu, click on "screen cages" in the list of links in the middle of the page, and then scroll down and the crested cages are at the bottom of that page.

from the site:
"CRESTED GECKO ENCLOSURE
23"x16"x16"
Cage with removable easy-to-clean PVC floor tray. Two front-access doors-one standard hinged door-one flip-top
Both sides are plexi glass"
