Counter-pressure bottle filler

Anyone use one? If so, which one? There are a lot on ebay, most come from ChinašŸ˜. I donā€™t think I can make one for less than I can buy it due to raw product costs. Suggestions?

I just bought the setup from Morebeer. I have the stainless mount made. Not really a beer gun, but it was the style that fit me. I wanted something more table top.

I have brand new one for sale. I bought a  kegerator and donā€™t need it nowā€¦never been usedā€¦from Williams Warn breweryā€¦make me an offer 3373228623 Michael Duhon
