The other day my regulator started acting weird. When I would hook it up to a non-pressurized keg, I would hear the gas go in quickly for a couple of seconds, and then it would slow down suddenly and creep really slowly up to the pressure I had it set for. Then today, the adjustment screw was almost impossible to turn. The last time this happened, I tried using graphite to help the threads, but I wasn't impressed with the results so I replaced the regulator.
Has anybody had good results with a regulator rebuild kit? If not, is there a good regulator on the market that is more durable than the standard units? My philosophy is to go ahead and spend the extra bucks up front, if there is a difference in quality.
