I've got a 35 and 36/51, both fresh from the crate. They are superbly crafted, pleasant to shoot, and accurate. It would be nice to have a more plentiful supply of ammo for them, and they do have their quirks, but I really like the guns. I seem to remember some U.S. site selling the grenade launching adapters to fire golf balls with blanks, that's a good enough reason to own one right there! I reckon they're worth at least 400 or 500 bucks, but you'd have to find someone who wants one; their not exactly rare or super desireable.
