Like Wayne, I've been on the buying and selling side as well.
When selling, my goal was to be totally upfront with where the plane was at. I set the price accordingly. It sold in 4 days.
I still have the website that I put together.

Buying (especially the first time) is hard-- no matter how much you think you know.
Remember the movie "Toy Story"? Every toy needed a "moving buddy" so they wouldn't get lost when Andy moved.
I highly recommend that you find a "buying buddy" when you decide to buy your first airplane.
Ideally, the buddy should be a past or present 150/152 owner with at least 1 year of owning time.
That person will have a different viewpoint on whatever airplane you think you want to buy. I can guarantee it.
