Do you look on Spotties.com and Spotties4sale? There are loads of appies on the market at the moment (maybe due to pssm scares?) Shame about that one, though - I do like Cid's offspring.
I think he looks nice, I don;t know how you can tell that he is strong from a pic, and he is being ridden in a snaffle. He could be green for all manner of reasons. The canter pic isn;t the best, but it does show excellent potential, he is very uphill and has really stepped under himself.
I looked at Whirlwindhorses because they breed spotty PBA's. If you aren't fussed about your project having spots, they have a couple of non-spotty, ex-broodmares for sale that need to be re-backed. I've done this myself and was very impressed how quickly the mares remembered everything (even after a few years of having babies) and how willing they were to become riding horses again.
