I decided it was time to build a 2 tap kegerator recently . Not having the money to buy an actual one I went with building my own . Now I know it's easier to build one out of a full size fridge and the nicer pre built ones run about $400 and higher .
The largest piece of advice is when your searchIng thru Craigslist or news paper . Ask for model #.
Mine is a Danby DCR412BLS. I then did a search for that model with the word kegorator . More than likely someone has looked into , built and posted a how to .
