Reptile basics cages are light enough to carry. You can order a built in light with it. you can choose your heat source. And they should work within the price range that you mentioned. I have one of them. Starmom has several. Smart people buylots of the same kind of cages for easy stacking. Dummies like me have to buy one cage from each maker to try them out.

I have a leopard gecko that I'm going to be outfitting with a new home after my ball python. I'm probably going to be doing the same.
