I saw the thread about stackable cages and thought I would add my 2 cents. I bought two 7 foot x 3 foot deep x 2.5 feet high from Boamaster. The cages look good and the prices are very reasonable - I paid $450 for each cage. I keep my 2 S. hispidus in the top cage, and my 2 red foot tortoises in the bottom. The nice thing about the cages is that they have holes pre-cut to accomodate wiring. The only drawback is that Mark from Boamaster uses a laser to cut the wood/melamine, so the cages had a sooty smell when I got them. I ran wet steel wool over the edges to get rid of the soot and the smell. They are great cages and look really good.
