I follow the 337 market very closely as I'm on the hunt for the right plane. I'm not in a terrible hurry, but will hopefully buy before the end of the year. Anyway, it amazes me how huge the differences are. Clearly many sellers are stuck in early 90's pricing and think that old aircrafts just appreciate, no matter how bad the times are.
This is an example of that:

$60K for a 11.500hr plane with a clapped out rear engine? I don't think so. Even at half of that it would be a struggle.
Good thing is I see a lot 337's coming on to the market, so there's plenty of movement. This will probably increase as time goes on. Rightly priced, they're a lot of airplane for the money. Which is why I'm interested. My funds are limited as a first time buyer, so time is all I have on my side.
