Fender Jazz Basses (or similar JB-shaped objects from other sources) in a used 4 are not that hard to find. With your back problems, I'd aim for alder or poplar, ash is going to get you into that weight range you don't want to be in, though there are exceptions. A quick flyby in Reverb a few minutes ago had quite a few FJB's used around that kind of money, and widen that search to other makers would yield a big selection.
I always suggest don't get in a big hurry and look for exactly what you're after, even if it takes a while, and I far prefer buying from a store instead of an individual, but all that's your business.
Yeah, I wouldn't want a Squier either.
. . . but then again . . .
