I sold my Freddy for $1800 about a month ago. Of course it had a repro glove flipper, NOS translite, a NOS decal set, NOS paperwork and several replacement plastics so that added to the price. Plus the buyer had been looking for one for a while. I would say $1300 to $1400 is fair for one in average condition. There were only a few thousand made. They don't come up to often.
The glove flippers were reproed. I got mine from Steve at PBR a couple of years ago so you might check with him to see if he still has them. I think it was around $75. It was well worth the money as it much more durable then the original. Even after several direct hits from air balls it still looked perfect.
