I walked into my LFS yesterday, and saw one of the most beautiful tanks i've ever seen. So after drooling over the plants for a while I start inspecting this guys equipment. Good filter, TONS of light (used a pinkish colored bulb mixed in), but then i look at his CO2 setup... He's got a very simple looking regulator with a bubble counter, and then a controller. Ok so far so good.
I get to talking with the guy who owns the place and maintains the planted tank, he's telling me all about the great CO2 setup he's got. He tells me that his regulator is by far the best part of the system - it cost him around $400-$600.
He was really pushing this setup and trying to get me to buy a whole setup from him. I've never heard of a regulator for planted tank purposes costing more than $220 (Which i only saw at another store where everything was excessively marked up).
So with all that said, my question is this: Given that you are using a quality pH controller / monitor that you recalibrate regularly, what is the benefit of a top notch regulator vs. say the Milwaukee MA957 Regulator (a perfectly adequate regulator IMO)?
I'm thinking that as long as you've adjusted the flow according to a bubble counter, and your pH monitor is well calibrated- why spend money on an expensive regulator. Less leakage with more xpensive regulators?? I'm all ears.

to see if anyone had previously discussed this...
