I just bought a Thorogood AP for $300 on craigslist. New it was listed for $450, the owner had only used it 2 or 3 times. I like it, my horse seems to like it very much.
My old Courbette AP I picked up at a consignment shop for $150, back about 1995, and I had it restuffed, some years later, for $250. It was in very good shape when I bought it, about 6 or 8 years old. It sold for around $800 when it was new.
