I'm wondering how many of you convert aquariums to terrariums and what type of screen lids you use. Is one type more secure than another? They're not too expensive, but could you make your own? Do you use the standard metal clips and are these sufficient?

Sly's tank was made for reptiles and the lid slides into place & locks with a little pin, but there have been so many inexpensive aquariums in the classifieds lately. The guy is being a little flaky, but I should have 55 & 29 gallon aquariums to pick up tonight I'm in no hurry, so if the guy flakes it's not the end of the world, but if he comes through I'm getting both for $30
