On other forums and facebook groups (will not name them, do not want to be banned)
we made a poll what is wrong with Chinese laser cutters ... I'll just put several opinions together:
Most of the Chinese analogues in the market do not meet the contracted power standards and are not powerful enough to cut.

CO2 is harder to set up (laser cannot be moved – mirrors must be used- they can go out of alignment);
CO2 cannot be carried around (see the problem above);
CO2 requires buying CO2 continually, as there is always some leakage;
CO2 requires compressed air for cooling;
CO2 is subject to export restrictions in most countries;
CO2 is very delicate (lots of glass apparatus) and may be damaged during shipping.

That is why we think that diode lasers, like Endurance L-Cheapo are more practical in this case...
