I am looking into buying a set of word sportsman II's from a fella, he said it dropped a valve as you can see in the picture, i was wondering how repairable is it and is it worth messing with in the first place? thanks. http://img176.imageshack.us/img176/8678/photo7zf2.th.jpg (http://img176.imageshack.us/my.php?image=photo7zf2.jpg)

Repairable (and cosmetic) damage, would be wise to pressure test it as well as magnaflux.
Whether it is worth while comes down to price. (doesn't it always?)
