I just got two 4x2x1 cages from repti-racks and i love them. I have my ball python in one and my SD retic in the other. The awsome thing is without the extra height, its easier to heat. And my snakes dont need the vertical space. But if your looking for some awsome cages, deffinetly look at repti-racks. 139 for a 4 footer is the best deal you can get. And the customer service is amazing. I usually get a reply without 15 minutes. And they have a 6 tub rack that fits as a stand that is perfect for the 4 footers.
