Looking at cheap alternatives to mini co2 regulators. Can an o2 regulator be used for co2 regulator and has anyone tried the kobalt mini regulators? Also, looks like you can get cheap regulators for aquariums?
Also, I am starting to see cheap new kegs in 3 gal and 5 gal sizes. Apparently made in China. I am also reading that the welds may contain lead. Anyone try these? Is the lead concern a myth? I would assume all welds have some lead?
