Personally I would avoid buying a bass from ebay unless there is a 100% return policy, how are you going to be able to check it out? As far as depreciation, yeah, the Jazz will continuously escalate, but the Stingray has excellent staying power financially. I'd go with the 'Ray just out of preference. They sound increadible with tons of tonal options and a solid design, plus a lil' bit-o-soul. Spector's are good if you're playing really loud and hard. I'm not a big fan of them because they lack character definition, really kinda lifeless and "flat" sounding. -*flat as in hollow tone, not detuned* All my opinion, of course.
