The forestry birds are normally very well maintained, so can be a good buy. They're all high time, though, and most of that has been spent low and in rising air, which puts a little more stress on the airframe. But it wouldn't worry me, just make sure you do a thorough pre-buy and maybe an eddy-current test. I seem to recall that the RayJay turbos are manual wastegate. Which is good in many ways, as you can control stuff and don't have to deal with automated actuators etc that tend to stick.
