re: Anybody ever used a Jockey Box at their tailgate?

Yeah everybody at our tailgate is 30ish and has small kids, but I was just thinking a small keg of Abita or something at a tailgate would be easier than all the glass bottles and stuff that we normally go through, and having it on tap would just be a nice touch. Still debating whether to buy one already built or make my own. I don't know alot about draft beer equipment, and I can get one already assembled for not much more than it would cost to build it myself...
