I'm in the process of building a keezer and messed up on my estimate of the size of my CO2 tank + dual body regulator, so I'm looking for a single body regulator. Thought I'd check here first to see if anyone had one they wanted to unload before I bought one from a retailer. Reply here or PM, it doesn't matter, just be sure to include details (brand, price including shipping if not local, etc...). Thanks.
