Product review (4 stars): Great kit!!!!
Great product.  Easy to install.  I am running two sixtels.  I could run tall 1/4s and probably run two regular quarters if I put in a shelf and didn't have a 20 lb co2 tank. Worth the money.  Unless you are buying a high-end unit, the conversion is the way to go.  The mini fridges are not cold enough.  Buy a fridge on craiglist or from the pennysaver and buy the kit. The unit will not look as sharp, but the beer will taste better.
