That would be a nice setup. Austin Homebrew had a good price on that regulator- I guess they figured it was too good! Anyways I wish there was a less expensive adapter for that regulator. The one on that engraving site is overpriced. O' well. I've been mostly satisfied with the large disposable cartridges on my 10 gallon. I found some 98g disposables at the local sporting goods store for only $5 each so I stocked up on a few of them. I'm also currently working on integrading a miniature solenoid vavle so I'm not wasting Co2 at night. I'm trying to get the service time on one of these cartridges from about 4 weeks up to around 8 weeks. $5 for 8 weeks of Co2 won't be as bad. That's less than fishfood.
