Need used prop, not to picky!

I'm looking for a used prop. Like I said, I'm not to picky. I have a real nice 14.5 x 14.25 right now. What I'd like, is a 14 x 16 or 14 x 18. I need something to put on when I'm just running up the river, or on a sketchy lake for a tie up. Something that's not going to break my heart when it gets wrapped up, and might get better fuel mileage or higher top end when just cruising around.

Thanks, Joe
