2 pressures, one co2 tank

[S-04]

I'm in the middle of acquiring what I need to turn my lagering chamber into a keezer, and I would eventually like to add a tap for soda water. From what I've been reading, it seems like if I'm going to do that I'll need a 3 gauge, dual product regulator:

Does anyone know any cheaper way to do this? Thanks!

I'm in the process of doing the same. Building a keezer that is. Honestly the dual product is the best way from what I've seen.

My plan is to put the inner hook up to a 3 way manifold then the other to what ever else. I plan on having stout on tap as I'm a stout fan. So the outside hook up will be serving my stout at lower psi and the inside to my manifold.

Seems to be the common setup from all the things I've been reading online.
