It's such a buyers market out there right now. I think this aircraft looks like a nice unit if a person needed the turbos. I wouldn't go for turbos unless I was out flying the mountains again and then maybe it would be justified. I have flown a normal through and over about any mountain out there. It a little underpowered at altitude (14,000) but it will take you safely. The turbos will cost you more in fuel and maintenance but if needed they are nice.

This is a little high on engine time but if they have been taken care of there is a lot of life left on these engines. There are others out there but the most important part of looking at any of these aircraft is a thorough pre-buy inspection by a experienced Skymaster technician. It will be the best money you ever spend.

I like this one too but it's a lot more money.
