Im sick of bottling and getting equipment together for kegging. I have been looking around at different regulators on amazon,ebay etc and see a huge price difference and I guess thats what confusing me. I have noticed some of the taprites the co2 pressure is changed with what looks like a screwdriver and others just have a turn knob. Other than that a dual guage taprite,are they all the same? Thanks alot for looking and posting replies. Cheers Dave
