But the point you are trying to make is that buying a used turbine is a waste of money
No, what I am saying is that buying a used turbine is not the best option for a person who is asking for reliability.
This is the original question:
I am thinking of getting a second hand JetCat turbine for a project of mine and turbine reliability is of paramount importance. How long do these turbines last on average?
and my final answers is:
Do the right thing and buy a new one if you can.
