I picked up the whole kit minus the tops for the bottles for $50 from someone selling his old kegerator parts. The tank lasts me forever and gives me about 45lbs of bubbles in a bottle. When empty I just swap out the CO2 bottle for about $30That should be a food grade CO(2) tank. The SodaStream cartridges are really expensive, and I'm not surprised in the least about 3rd party refills or kits.
I have made (and probably should start again) making sparkling water in my kegerator. It's all a sunk cost, so it's just costing me a tap space which is fine, because I just don't have anything else on them at the moment.
