Hahaha this is cool! This is the Allavino CWR271-1BB from Beverage Factory. I only know since I have the same one for storing wine :)
Looks like Beverage Factory has it for $849.99 plus Free Shipping: http://www.beveragefactory.com/refrigerators/wine/allavino_CWR271-1BB_wine_cellar.html
Yes, I've purchased the Kegco 542 regulator and it works great!!!! I ordered it from Beverage Factory since our old regulator died and not only is the regulator great but the staff there were friendly and helpful too!
