Best Prices on CO2 hardware?

There seems to be a LOT of difference between dealers when it comes to CO2 hook-up hardware (splitters, line couplers, etc.).

Who has the best prices, overall?

I have a dual regulator setup, but plan on having either four or six kegs on tap, eventually.

I haven't dealt with these folks yet, but it would seem one could cut out a couple resellers buying from them
CHI Company ball lock kegs for sale, Home brewing and vending, beer kegs, Pepsi vending machines, flavor strips and vending labels

I actually got a pair of kegs from them just today. They are a little nasty on the outside, but they arrived pressurized and they included two complete new sets of gaskets.

VERY good price, too.

The main thing I am looking for is a four port CO2 distributor/manifold, whatever you want to call it. I want to split a CO2 line for four kegs with individual shutoffs. It looks like it will be right at $40. I found a plastic one and thought it would be less expensive, but it turned out to cost more than a brass one.
