It's more hours thatn i'd like, but it doesn't mean it's worn out. I was always under the impression that 6,000 hours is the point where the motor starts to get lazy, but it also doesn't mean it won't still work, just harder to start.
If the price is right, check how it starts when cold. If it starts well, and the pivot points are tight, there is no reason why the machine will not be suitable for you.
I had a machine with 6,600 hours i think, it was hard to start, but when started, it went all day long without issues.
If you don't plan on doing a lot of work with it, i'd go for it. Being fairly high hours, you can use this as a bargaining chip to get the price down.
