I don't know, I just picked up 6 kegs as part of a parts buy from a local CL add. I grabbed 6 kegs, 6 taps w/shanks, all hoses and fittings, 5# bottle, 15# bottle, regulators, temp controller, and a keezer for $450. I figured I would have bought the kegs and taps for that price eventually anyway. An extra fridge is always handy.
The deals happen. I didn't haggle with the seller because it was a very fair deal. This is what it was. http://gulfport.craigslist.org/app/3172239246.html. I'd keep checking CL for the local cities near you.
