Anything in particular I should look for? Saw a few youtube vids and it seems pretty popular. I want to start collecting some of the WWII era guns and this one seems pretty cheap on AIM? For $69 is it worthwhile, or something in awful shape. Just looking for something to take to the range every once in awhile. Also, whats the difference between the two on AIM's site aside from one being hexagonal? What doe that even mean for the rifle?
