Title: parts issues...
Review: Had mine for about 1 year, regulator stopped working and it turned out to be a stripped screw under the regulator knob. Guess what? You can't buy a replacement nut and screw, you have to buy the whole ($92.00) regulator manifold assembly! Of course the nut and screw are "special" (left hand threads, square top...). I'm switching to Makita...
