Hmm...
I got mine from pvccages.com.
It is a 4x2x1.5 though, with a divider. It was $240 after box day, but if you go on Kijiji there should be a distributor in your area that will give you a much better deal - that's how I got mine!
You should be able to have the corn as an adult in a 2x2x1 (which should cost you under $200 easy).

Best of luck!
