Draft & Kegging Specials - July 2009 | MoreBeer
Scroll down and you will see it on sale.
I got this one from morebeer last week. It is on sale for $43, I have another one just like this that works fine. If you grab another few dollars worth of items you can get free shipping as well. You may be able to find it cheaper on ebay eventually, but this is a pretty good price if you need it right away.
