Sushi dude..
My O2 tank was free given by someone but it costs about rm90 to convert the valve for Co2. If you are looking for small ones, you can easily buy 2-3kg ones for less than rm300. I suggest don't bother about the aluminium ones, since they are too expensive. I have one 500g Mr Aqua aliminium cyclinder for backup, it's light but I find the valve too sensitive and spoil easily. Btw, kg or litre(1kg=1litre) is the amount of gas that can fill the cylinder and not the weight of the cylinder.
