Just bought one from beveragefactory.com, it's called a Guinness Beer Faucet... around $100 bucks. Really good quality faucet. Had a welding gas tank and traded it at my local gas supplier for N2/CO2 mix, it was around $45 just for the gas, and actually drinking my first chocolate oatmeal stout right now... it's a little undercarbonated still... but it should be better in the next few days. I just posted a thread with some questions on carbonation. Anyways... I recommend you try it out! Worth the investment.
