you can get the mini "propane-torch" style oxygen tanks at Lowes or Home Depot, check with the soldering equipment. Supposedly you get 10 or so batches from one 8 dollar tank.... that's what i use.
30 seconds of oxygenation, and you are good to go.
Brewmasters warehouse has the regulator kit i use:
