I was lucky enough to have a breeder in my area sell off a bunch of his sweaterbox and 41qt boaphile racks.
I got them dirt cheap and instantly - two big reasons why I have avoided ordering from Boaphile in the past.
As far as comparing them against Reptile Basics - Rich's product is thicker and sturdier.
If Jeff began producing Boaphiles for the same price as Rich, with the same turnaround time, I would still opt for the Reptile Basics rack.
Animal Plastics has quoted me some long turnaround times when I have spoken to them. I got one of their racks used over Craig's List and have been impressed with the quality.
Rich at Reptile Basics produces a quality product without the long wait times. He also provides some of the best customer service in the industry. You can't go wrong with him.
