Just inserting my advice/experience. GO with someone who can make (or already has) units in the configuration that you want. I bought a "cheaper" regulator that lasted me for a while, but when I got to the end of my CO2 tank, I learned the hard way, that it was NOT a dual stage regulator like it was claimed to be. It dumped the CO2 at the end of the tank and I wound up losing all of my critters in the tank (happened during the day while I was at work).
After that, I went out and bought one of bettatail's set ups and loved it so much, I asked him to make one for me to run multiple tanks! I'm not gonna try to lie to you, they are not cheap, but his quality is AWESOME! Not only does he assemble them, but HE TESTS them before selling them! THAT'S the kind of piece of mind I don't mind paying for!!! Also, I've not really had to make too many adjustments over the years either (mostly because I've decided I wanted to increase or decrease the amount of flow to my tanks). I've also heard great stuff about Old Punk's builds as well! I hope that this helps!!!
