I just bought a brass check valve from on-line an a quick question
of where is the best place to put in-line at?

1. closes to the regulator with bubble counter
2. or 3 feet away next to the in-line co2 diffuser

That is also what I have heard, don't know if it really matters. I use the screw-ons with all my builds.... just attaches directly to the needle valve, never had any problems or complaints from buyers,

I have never used a brass CV but on my riggs I have a CV close to the water and one before the regulator. It just makes me feel better.

Are the brass CV's worth the extra $? If they are I may just have to buy 4 and replace the plastic ones and the knock off ADA ruby CV with them.
I've use the plastic Dennerle CO2 Check Valve they are good German made but they are expensive , Had them for a couple of years now so I end up wanting to try the brass ones I pick up on eBay for $4. ea x2 I paid $25. for the Dennerle CO2 Check Valve.
