I don't know where to refill paintball CO2 cylinders in Seattle anymore. I used to do it at Butch's guns and used them for my portable homebrew beer setup (which I just sold on Saturday). I think you have to go out to the 'burbs now.
You could build a system that used a 5lb welding CO2 cylinder, they are easily refilled at Central Welding. It's common homebrew equipment to make fizzy water (instead of beer) using a soda/homebrew 3 or 5 gallon keg, CO2 regulator, and CO2 cylinder.
