Product review (5 stars): Great deal, works perfectly!
I was able to set up the Keg-O-Rator in about an hour, for some reason mine did not come with an instruction manual!  Luckily I found a PDF download at the bottom of this page: [...]

Even the improved instructions are a bit frustrating at first and could be clarified more, but once I got the feel of what pieces are what it wasn't too bad.  I had no damage in the product at all.  The 2.5 lbs co2 tank should handle 6-8 1/4 bbl kegs, I was told.  Today I tapped the first 30 liter keg (Double Mountain IRA!), set the PSI to 8 and it's pouring sweet, sweet draft beer with just the right amount of head.

Very happy with this, and I'm looking forward to many great brews! (I'm lucky that I live in Portland, with the best selection of micros you could ever ask for!)
