I would be asking about warranty on the laser tube. I have known of other people with Chinese machines, going through multiple tubes in a year. Maybe they have gotten better recently but I doubt it. Generally the old style metal co2 tubes have a 5-7 year lifespan. The newer ceramic tubes are touted as lasting up to 25 years give or take and even then it's the electronics that die not the tube itself. I would not even consider a glass tube, however I'm not sure what is sold in the cheap machines at all so can't offer any advise in that regard unfortunately. If you do go with a cheaper machine you would really want a fairly decent warranty unless you have a a healthy ongoing maintenance budget. Good luck!
