Don't be too quick to ditch that climb prop. One of the 150/152s marginal areas is it's climb performance. My prop is pitched to 48, I wouldn't want to go any flatter than that.
A new prop will cost $2,500 to $3000 depending on make, you may also need a new spinner and bolts, tax too
Sale price of your old prop is dependant on age, condition, finding the guy who needs it etc!
