Just to update. I got a lot of responses from breeders. Amazing how many are actually breeding non designer. My price range of $400-450 is spot on actually. It's too cold this winter to ship and establish a neonate but I have one I contacted and we are working out reserving his next clutch once it gets started this coming spring. He actually has a few he is holding back and may let one go so I might get a 6-9 month established one sooner if the weather warms up.
If anyone is looking into USCBB GTPS, they are not rare and not expensive for what they are. If you are willing to wait, you can get an aru or biak for $400 from a US breeder.
