Quoted from ForceFlow:AFM prices were dipping even before AFMr came out. They don't seem to be fetching $7-$8k any more for nice/restored examples.
I might even suggest dropping into the $4k range for a player's condition pin if it doesn't move at $5k. For just a bit more now, you can get a brand new AFMr, so people may be less willing to pay a premium on player's condition AFM's.
