Joon, another option is to simply purchase a regulator from a welding supply store ($30-40) and a quality needle valve ($10-20). You can rent CO2 tanks from welding supply stores for about $10-15 dollars.
If you want to do it on the cheap, you can set up a complete and functional system for well under $100.
