I would second Brian's suggestion about the Campbell prop. You could always go with a Michigan Bronze prop (not brass anymore thank god).
But they are more oriented toward the power boat market, and the blade shape of their props is not ideal for a displacement boat IMHO. Think of the old Dyna-Jet Chris Craft style. Campbell is better I think.
Not sure where you are, but is a prop shop an option? There are several in the Annapolis area including the Digital Prop Shop down at Herrington Harbor North Marina in Deale, MD. The owner there (forgot his name) can verify the proper size and pitch using his software and he distributes a perfectly fine bronze prop line. If you've re-powered, or your engine has a different power curve than OEM it will be important to match the right prop (as I'm sure you know). I think my 14" would have been about $375. Didn't buy one from him but he was quite helpful. Good info on website too.

My best prop fit so far is on an 8500# sailboat. I went with a nice Columbian Bronze prop 5 years ago that had been balanced and cupped. I found it in MD at a rather quirky yet cool consignment shop, Small Open Boats in Leonardtown, MD. Really nice folks.

A word of caution, I would be leery of buying a used prop without having it balanced because of the unbelievable grief a bad prop can wreak on the drive train.
Also, if you are going mail order, I would be absolutely sure you have the correct rotation and hub taper.
