I don't know how 'new' the saddle has to be, but have you tried Buck's County Saddlery?
I just bought a used Crosby Prix de Nations -- plain flap, no rolls, CC -- for $250. I was looking for something with plain flaps for my lessons, since the knee padding was bothering me, and tried the eBay
route, but wasn't sure what I'd be getting. I looked at Buck's, looked at ended auctions on eBay and then compared the two to see what kind of saddle I could get in my price range. In the end I went with Buck's, since it was a fixed price AND they let you do a trial ride to make sure it fits and is to your liking.
Just a thought.
