Last summer I sat in the Channel and listened to the sales pitch from the guy who built the first Domin8er, he had a 23'(I think) with a cuddy/open, the boat seemed big for a 23'. He told me he also made the hulls for Cheetahs, so I'm sure they are pretty well made. The boat looked real clean and well put together from what I saw, but that was after a six pack(at least).
As far as other boats, how big are you looking @ for 50-60K?
Try Barry @ Shockwave (909)898-9360, I'm sure you'll be pleased and if he doesn't have what you want, he'll point you in the right direction.
Good luck!
