I currently have the Milwaukee MA957 regulator. I cannot get a constant BPS no matter what I try. I am almost positive this is where my BBA problems are coming from. I am done with this and am looking for another needle valve. I am also willing to ditch this entire product and get a whole new regulator, bubble counter, needle valve, etc. Can anyone recommend an entire setup that is high quality and accurate. It would be great if someone had the entire setup ready to purchase. I don't have very much experience with all the different parts, and ordering piece by piece doesn't sound appealing. I am willing to spend whatever it takes for a good setup that I can rely on. TIA.
