How should I set up the gas for my keezer?

I've got a 7cft keezer with four corny kegs, two empty, two full sitting in it right now. I am trying to determine how to set up the gas for my keezer. Looking for suggestions and comments on how you like your current setup.

Here is what I would eventually like to do:

- carbonate beer (now)
- dispense beer (now)
- dispense soda
- dispense stout running on nitrogen

I've seen a number of different setups as far as manifolds and daisy chained regulators, but I am wondering how many of you use the same regulator to dispense different styles of beer?

You can't dispense soda and beer with one regulator. I have a primary set at #35 for soda, which supplies the two secondaries. One secondary is at #12 for most beers and the other at #2 for "real" ales, wine and cider.

This looks like a pretty reasonable way to set things up David. I like the idea of using the two port manifolds because you can hook two of these together. I looked at some inexpensive regulators and wondered if anything at HF would work. As another user on the board pointed out in this thread https://www.homebrewtalk.com/f11/finished-my-kegerator-28512/, the one for Air Flow will not work, but the one for air pressure will. The appropriate gauge for the ranged we are interested in would also need to be added.
