I'm with above...
I have a single pressure dual gauge reg and I am now trying to turn it into a dual pressure reg. I like stouts which are around 3 to 5 psi and the other ales I make are around 10 to 12 psi. If you are hardly ever going to make anything out of the 10 to 12 psi range, go with the single pressure reg and use something to split it.
