I'd prefer to get something that doesn't require for me to fiddle with it on a regular basis. I'd love to have something that I can just set and forget along with few check up when necessary.

I've decided that I'd try give the local CO2 parts around here. Where would these be found? My first thought was welding store, I could look that up... but what else?
I figured that I'd try looking around first before I restort to buying supplies online. (if $ is reasonable though)

Thanks for your help guys.

Thanks nursie for the welcome
