If the OP is (and many other TB members are) like me, no matter how much he drools after a bass, once he has it for a few months it will become "just" a goto bass, no more and no less. Said differently, the special thrill of playing it vs. any other fine bass he might have in his stable will largely be gone.
As for pre-CBS Fender basses, yes, they're very expensive. In my book too expensive just to get older/ dryer wood and a bit of that early Fender mystique. BTW, it's been pretty well reported that some pre-CBS Fender are stinkers and some CBS Fender are quite good. A lot of it comes down to how wood, metal, ceramic, etc. come together on any particular instrument. AKA, luck..... Some of this is evident by how desirable 70's JBasses have become thanks to the likes of Marcus Miller and Geddy Lee.
