yes, there is one kel-tec sub 2000 owner here.
i like mine. it's unique, and low priced. some have a hard time getting their cheek down far enough on that straight tube.
the folding option is hard to beat. check out this board.
i just got a cobray cm-11 9mm carbine. haven't shot it yet. i also like the 9mm carbine. too bad there aren't more options.
was thinking of getting a marlin camp 9 and a bull pup stock.
