Fizz-Gizz looks great, but those dinky 16g cartridges can't hold many soda-bottle-equivalents of CO2? You get a single cartridge with the Fizz-Gizz, won't you have to refill it constantly?
For comparison, my home carbonator (AGA, not SodaStream, but same principle) has a huge 425g cartridge that yields about 60 liters of carbonated water.
In other words, it takes about 7g of CO2 to saturate a liter of water (probably more as these countertop machines aren't very effective at saturating the water), meaning 16g should give you barely in excess of 2 liters of carbonated water. That's more or less how much I consume in a day.
