NeedThomas 4101 Compressor

Where is the cheapest place to get a Thomas 4101 Compressor at. I have one on my truck now, but I rebuilt it and its still not running correctly(yes I rebuilt it right). I'd like to stay with that model, because of the speed. FBI has it listed for $399 in MINI-TRUCKIN. Does anybody know if that's the best price, or does another company have them cheaper?

Thanx in advance
