Cages
I wish that I could build my own cages like Will and Zerah, but I have no talent in that area. So, if you're like me and cannot build your own cages, then I agree with Brad that cages from (LDS) cages.net are worth a look. All my adult cages are purchased from them. Their large mesh option makes their cages ideal for adult chams. And I just learned from Dave Weldon, that LDS offers an option for a bottom panel opening. By the way, Dave's setup is awesome.
For small cages, I buy 4 at a time from LLLReptile. My experience with Reptile Depot has also been discouraging. Orders from them can take sometimes 2 to 3 weeks to arrive, whereas orders from LLLReptile arrive in 2 to 3 days!
