What I hope to be the last co2 regulator for a while. Finally got tired of getting cheap ones from allmamoneyzgone and went with the komos one from morebeer, with the guard. I've broken three from falling over (no I didn't learn after the first one), and the last one I got arrived pre-broken for my convenience. The Komos isn't the best (could not condone spending the $$ for the taprite) but arrived in excellent shape, with a duotight adapter. The guard is very heavy duty, with some sharp edges that I'll smooth out with my dremel when I get around to it; that regulator ain't gonna break unless I drop it from a height. Should note that the previous fall-overs happened because it's my 5lb tank, gets top-heavy and sometimes I don't put it in a safe place. 20lb tank is wedged between the kegerator and a standing cabinet that even the dogs can't knock over.
