I just got a soda stream, i'm curious to find out if it's practical to fill it myself. It costs $12-14/refill at retail, it's about $1 worth of gas, max. The old razor and blade model, except I paid $150 for the soda stream machine already.
There are plenty of posts online about getting big CO2 tanks, getting the right adapter, setting it up, but none are idiots guides. Other guides say just get this adapter then have them filled at a paintball store. I'd be happy doing that, just buying the adapter, it sounds much easier than having a full CO2 rig at home, but paintball stores are a bit hard to come by in NZ.
Any thoughts or tips?
