Jake, there's a brew store here in Moncton that bought a bunch of 3 port manifolds and were charged too little from the company, and they are selling them for $42.99 each. I can pick up a couple for you if you want. will be cheaper than buying online with the shipping.
JohnQ also just ordered a bunch of inline regulators and small check valves...you might want to ask him about those. He ordered 3 of each for me for my 3 port manifold. I'll probably run my manifold main pressure at 40PSI, and adjust each of the gas lines with their own inline regulator.
Sounds like the type of setup you're looking for, only you want 6, not 3.
Let me know. I'll grab a couple and bring them up next weekend....should be able to make the meeting on the 2nd of oct.
by the way...you'll notice on hopdawgs that they have manifold ball valves with builtin check valves for $11.95. But like I said, JohnQ ordered up a bunch of little plastic check valves for a couple of bucks each.
