Product review (5 stars): Great deal for the money
I've only been using this kit for a couple brews so far, but it's holding up great.  The 5 lb CO2 tank was less than a month old, but I didn't use it; my LHBS was happy to take it in on trade for a slight used 20 lb tank.  I purchased an additional regulator (Kegco 541), additional ball locks, lines and tap directly from Beverage Factory.  Make sure to get a left hand threaded nipple to daisy chain additional Kegco regulators.

Gauges seem accurate, they are a little touchy, but not hard to master.  No leaks in the system that I can tell.  Looking forward to upgrading to 4 kegs later this year and planning to stick with Kegco and Beverage Factory.
