You can get some really cheap lasers direct from China on Ebay. But I read posts everyday from someone that has a tube problem, power supply problem, software problem, and no or extremely slow help from China. You'll also read about laser life as low as 100 hours. That's a lot of 30 second name burns, but the tubes also degrade just sitting there with no usage. There are companies in the USA that resell Chinese lasers with their own software, or upgraded laser tubes. That would be the only way I would buy one of those machines. You won't save any money if it just sits there like a paperweight if you can't get it running. You're going to hear a lot of the opposite opinion, but a lot of those people can tinker with electronics. Me? I need my hand held around these machines at the start. When a computer is involved, I still get a knot in my gut when I get started around a new machine. Maybe because I ran that CNC on the day job, but I just saw a lot of trouble over the years from something as simple as a corporate software update that should have had no effect, but did!
