That's my tank and regulator.. I just switched to a 20lb tank. I was going to use the 5lb one for nitrogen/beer gas but my nitorgen valve won't tread in it.
This tanks needs a hydro test done ($35 at Atlantic Alarms).. Some places might fill it back up without being retested first but they won't.
I'd be happy with $40 for the regulator and $40 for the tank..
