That is the downside of caging. The wait time can be long. I've heard Boaphiles can take forever, but again if you check some Craigslist adds or some other classifieds you may find your style of cage for a good price.

I read someplace that the PVC cages had the least amount of wait time, but they are a bit more $. I e-mailed Jim at PVC when I was looking at some perch ideas. He was pretty prompt and polite in his responses. You may want to check them out.

Good luck.
