CO2 4-way Distributor

I in the market for a 4-way distributor for my keezer project, and was going to try to build one myself, but I am unable to find pricing on the parts that would make it worth my time to do so. Do most folks buy or build?

I got mine when I ordered my keg stuff. if you price the check valves,its cheaper to get one pre made. At least from what I found.

If price is an issue, you can get away with using three plastic barbed "T" fittings.

I did that as a temporary measure and am still using it two years later.

Buy one because (almost) all of the ones meant for use as a CO2 distribution manifold have checkvalves built into the attached ball valve shutoffs for each output line. I figured out the hard way that checkvalves are really necessary unless you want to spend a lot of time cleaning and drying out your gas lines. Beer will flow back from a full corny into the gas line if the corny is at a higher pressure than the gas line and fitting itself, especially when the regulator has been taken off the tank because the pressure in the lines is gone. The tinyest amount of beer in the gas lines leads to gunk and mold in them.

Anything you make from hardware store parts won't have checkvalves.

Not sure if you expect to have to expand at any point, but I recently ordered (though haven't received yet) the modular manifold from Morebeer.com, because under their clearance section the expansions for it are half off. I just got the smallest (2) manifold and 2 expansions. It comes out about the same, but in the event I decide to grow down the road it'll be easy to add on I figure.

I saw the expansions and just bought several of those. I should only need a plug and barb fitting to complete the manifold!

This seems quite expensive to me. I built one myself for like 15 bucks using a manifold for air tools and some barbed fittings. Check out this thread to save a few bucks!
