OP - I just bought a kit online at adventures in home brewing. Otherwise I would have bought a kit on Craigslist. There's one in the Charleston area for $150 that I would have gotten if I hadn't already ordered mine. Not sure how close you are to charleston.
Online kit cane with one ball lock keg, one regulator, 10# co2 tank, tubing and a picnic tap. $170+shipping.
Craigslist kit came with one keg, one regulator, two co2 tanks, a big rolling cooler thing with a tap, I'm not sure on sizes or anything, but at $150 asking price doesn't hurt to call. Also, he's been reporting it every couple of days for over a week, so I'd shoot him a lower offer. Just search for kegs in the charleston area.
