chinese co2 laser question

Hi All,
Got my cnc router done and making money with for some time now, most
of the work I do is for vaccum forming moulds out of ranshape and MDF.
I'm ready for the next project, a laser cutter, I think having a cnc
laser cutter would be a nice adition to the shop.
Anyway, I'm about to buy a chinese made 80w co2 laser tube + power
suppy + mirros and lens for 1130 buks(shipping included).
The chinese says it should last for 1000 to 2000 hours before it
needs to be replaced.
Does anyone has one of these to give me some feedback?

Fogassa.
