Hi,
Here is what I have that might fit what you are looking for, and if so, I can take pictures. I think all of this stuff could be boxed up and sent to Chicago from Philly (where I live) at a reasonable cost. If interested then we could figure out pricing. So here is what I have:
1) CO2 dual regulator. It's a bit beat up but works well (I have it hooked up presently to one keg, but this dual regulator has two ports so it could connect to two different kegs at the same time without a gas manifold).
2) CO2 dual regulator. Practically new, but has only one port to connect to a keg, so you need a gas manifold to splice it so it could connect to more than one keg.
3) A Sanke keg coupler to connect your gas line to a commercial keg, if you want one of those.
4) A two tap beer tower to attach to a kegerator. I only have one faucet to go with this, so you would have to buy a second faucet.
5) A one tap beer tower to attach to a kegerator. Not sure why you would want this since most kegerators come with something like this, but I do have one!
Let me know if anything strikes your fancy and we can go from there.
take care, Ken
