The Darby Model DAR440BL has been used for Kegerator conversions and is available from walmart.com. According to the website, it is in limited availability, but can always be shipped to your store free.
I have not converted this fridge, but if you search HBT you will find others that have converted it.
Ordering ship to store at Walmart is easy and painless. I purchased my Sanyo from them several years ago, receiving it much quicker than they estimated. Be sure to check for shipping damage.
