One additional bass that you might want to add to your list to check out is the Road Worn Jazz. It features the same spec's as the 60's Jazz (on paper at least) but beyond the 'distressing' & the nitro, a lot of people agree that there are noticible differences (rolled edges on the fb, *edit in* lighter body, & so on) and that the hardware may actually be improved. I've heard nothing but good things about the RW stuff (once people got past the faux-mojo), and in fact, I'm getting myself a road worn P in about 2 weeks. (Edit - I was initially looking at the 50's P, which I loved the fit, finish, feel and sound on, until I found a road worn, which just took it everything about the 50's P to that next level, but with no glossy neck.)
Good luck.
