What size are you looking for? They have just come out with some new stackable breeder cages that are 48X26X14 and at $199 shipped they are a steal. They are also coming out with some that are 72X28X16 for $299 shipped. Here is the link

I have one of the giant display cages that they make and use it for my male burm. It is great. I wished I had gotten the shorter one, but once I figured out the heating in it's 44" height expanse it is perfect for the big boy. I like them even though they are a little pricey. They are very durable and light. I can move my big one by myself up and down the stairs in my house with the glass removed of course. It seems that they are trying to compete with moonstruck (which are crap. I got one for free and that is all it is worth) and animal plastics prices so you may see their prices dropping alot in the near future.
