A few days ago I was poking around Gunbroker -not really looking for anything in particular, if you can believe that- when I stumbled across this HP25 with a 5" barrel being offered as a parts gun. The starting bid was only $40, and shipping was a very reasonable $10. I ended up getting it for $62 shipped. http://www.gunbroker.com/item/642981287
The seller doesn't elaborate on what's wrong with the gun, but I've got quite a few spare parts so I'm pretty sure I can fix whatever ails it. If not, I can always send it back to the mother ship.
Since eventually the links to Gunbroker auctions go away, here are a few pics.
