I've got the 4 way manifold from Keg Connection. Works well for what it is, the check valves are great. One thing I don't like, is the shape. I could have routed my CO2 a little neater if they'd all been in a row.
Thanks for the input! I actually did buy a 3 way secondary regulator and once it arrived I found that it doesn't fit in my kegerator with three kegs in it. So I am actually selling it on the classifieds of this site if you are interested.
That "manifold" sure looks like a harbor freight air compressor distributor that they sell for $1 all the time. I got a couple of them, though not for my beer.
