I just bought 4 ball lock kegs, 5 lb co2 tank, old single gauge taprite regulator, 3 gas in disconnects, 1 liquid disconnect, 3 chrome faucets with commercial brand tap handles, sanke tap, European style tap, 2 other unknown (to me) commercial taps, plus bonus 5 gal glass carboy, 1 gal glass starter jug and a copper wort chiller for $215 from craigslist.
I need to get more 3 liquid disconnects, 1 gas disconnect, some gas hose and all the beer lines, as well as a manifold as it just has a 2-way splitter for now. Another $100 will hopefully have me setup.
Were it not for that deal I would have gotten the basic 3-keg pin lock kit from keg connection for $250. Honestly I'll probably sell the commercial taps and the faucets since I'm not converting my freezer for a while and will use picnic taps.
