Yes, I used to have a SodaStream until it broke. Very useful, but
probably a lot more expensive than shop brand soda nowadays. (ASDA
lemonade 35p for 2l; ASDA cola, 6x330ml cans, £1.50.) The SodaStream
does avoid the need to cart lots of water home, though.

If you are of a DIY mind you can fill the cylinder by unscrewing the
valve and fill with dry ice to the same weight as CO2 contents and screw
the valve back in, It will then sublimate to liquid gas
