a friend of mine just gave me 2 nitrogen regulators!!!!! big time score!!!! already on my way to having a nice stout setup!! plus i also just got 4 copper pipes, 5 feet long, 1 1/4" dia. looks like i'll be building my own RIMS system. and i got 7 ball valves to fit the pipes and a smaller ball valve for my mash tun. i got all the copper tubing that i'll need for my mash tun. ALL FOR FREE!!! just wanted to share my joy with my fellow brewers!!!!
