Converting from commercial kegs

I'm looking to get into kegging my beer so I don't have to worry about bottles and all that and I'm wondering how much would be required to convert this kit I found on craigslist to use with Carney kegs?


"Complete beer keg dispenser. Includes 2 CO2 Cylinders, Regulator, Tap, and hoses. Refrigerator accommodates 1/4 kegs of the Genny style. Will not fit Budwieser type kegs, but all of the plumbing can be put into any larger refrigerator to use with 1/2 kegs any style."

Converting a commercial style sanke kegerator to tap corny kegs is pretty simple. All you need is the two corny fittings, one for gas in and one for beer out. I think they run about 8-10 bucks each. Oh and a couple of hose clamps if you use the slip on type fittings.

I just ordered this for my keggerator, that I've had for years for commercial stuff...(and now homebrew), from Williams....

They're asking 75 dollars for it, (Including fridge with tap on it) is that a fair price, I'd have to pay 30 dollars for the kit to convert it, plus 30 to 40 for a keg.
