Heck, if you want the cheapest way out, get an NEF pardner pump protector. Its pretty much a Chinese 870 you can get for cheeeeeeeeeeeaaaaaaaap.
+1. Swing by Dick Sporing goods and walk out with a brand new Pardner for $200. Will take most accessories that the Rem. 870. Oh, and you'll have to take the rod out of the shell tube so you can hold five in there.
