I knew someone who purchased 1/6 barrel kegs from the Iron Horse Brewery. The problem was that I was set up for Cornelius kegs with ball-lock disconnects. I found this helpful video through Keg Connection detailing the conversion.
Two points of interest from my experience. The sanke tap barely fit into my kegerator. If I had to do it again I would get a low profile sanke tap. Second, make sure you put a rubber gasket or O-ring in the liquid out stock of the tap. I had major leakage problems until I did.
