If you go into trade servers, I think most will offer them for about (I think) 1-2.33 reclaimed metal or, on a few occasions, might even give you the key for a Strange variant of a weapon that they've been looking for. I usually don't go into trade servers though, so you might have to see what the actual prices are.
