Counter-pressure bottle filler

Anyone use one? If so, which one? There are a lot on ebay, most come from China😐. I don’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 don’t need it now…never been used…from Williams Warn brewery…make me an offer 3373228623 Michael Duhon
