I've had a good recent experience with Noble Reptiles. I believe they were vending the Raliegh NC show (the last one) and may be doing so again. I think they are located in Arkansas, but am not sure.

She communicated well, answered questions about feeding, etc. and shipping / payment went well. The animal I got from her was very healthy, eating like a champ, and mite-free. I'd buy from her again.
