I recently bought a 50's Precision from Musician's Friend, as someone noted they can be had around $600 when on sale (more for lacquer finish models). It's a maple board, and I have rounds n it, but by dialing out the "tone" knob you can get a very fat, low-treble sound. I do like the 50's classic P with rounds better than the MIM rosewood P with flats, even though that latter bass has an upgraded pickup and bridge.
So, I'd say Fender Classic 50's P in poly (rather than lacquer) finish would kill. I like mine a lot, better than my other (MIM) P which is rosewood/flats/nicely-upgraded components.
A friend of mine just got one of these and it's a really good bass, really nice MIM price too.
