bai kloy,
if youre interested in a used co2 nga sera. Naa koy kaila pero tank, solenoid and diffuser ra pero all sera. i think pwede ra mahangyo ug mga 4k. naa pa pakapin nga timer switch nga generic.
brandnew items would cost about you about 7k. but you still have to buy a regulator... i think mga 2k+ not sure though. a new co2 kit with regulator ang tank is around 13k na, last time i asked. sulit gihapon at 6k+ with soleniod pa.
