How does this tap system compare to the Heineken Draught Keg? I have bought a couple of those and found them very well presented. I'm not a huge Heineken fan, but the system was great. Holds about 1 1/3 gal., a bit more than half a case of 12s. Pricey tho', around $20 in these parts. But a cheaper domestic should be priced accordingly and might get my attention more regularly!
