Durable BB Water Pump? 74.

...Re-dissasembly in a year or two due to a low grade pump will just mar up the fresh parts so I would like not to get back into it for some years to come.

Well, while I understand you have zero desire to pull apart half the front end of the engine from over the fender (understandably...looks like an *** pain), there's nothing saying that the money you spend won't let you down, nor the money you save will doom you. I'd personally just go with a new manufacture parts store pump with a lifetime warranty, unless you need something special like a polished piece.
