I'm going to go back to the original question because I've been having the same thoughts - with a focus on a specific aircraft. Obvioulsy nobody here has done a pre-buy on this airplane, but given the specs, is it reasonably priced?

That's 3492 total time, 100 smoh, $14,500 for a basically bare bones 150H that I could probably keep at a grass field a couple of miles from my house.
I see this and it feels like a relatively good deal, pending a positive pre-buy. As an extra bonus I'd get to fly it 30 hours across the country to get it home.
So what do you think about the 150? There's always other aircraft models that you can pick and maybe should pick. But for the price, is this reasonable or does the relatively low price alarm you?
