If you can find an old 80's MIJ Squire, grab one! I was so pleased with mine it became my #1 player over and above my Rickenbacker 4001 and Gibson EB2-b and Fender Tele bass. THAT good! This was not uncommon with the early Squires, and they should be expensive. I still have it and it still plays great (needs some love in the pots and shielding dept.from beer spillage, etc.) With many of these Squires its a matter of trying a bunch of them and maybe getting lucky, but the MIJ Squires were usually all pretty good.
It's true those early 80s MIJ Squiers were excellent instruments. IMO, better (in general) than the Fenders being produced at the same time.
I used to have an MIJ Squier Telecaster (guitar) and an MIJ Squier P bass, both from '82 or '83 and they were great.
The market has caught up with them a bit and they have gone up in price, but you can still find them for ~$400 which to my mind is a steal.
Again, IMO, the heirs to that level of Squier quality are the current Classic Vibe (CV) line. There's also a Squier "Vintage Modified" (VM) line, but in my experience the quality control and some of the appointments of the VMs are not as high or consistent as with the CVs.
I've played some great VMs and some that I felt had some issues, but EVERY Squier CV I have played has been very, very good. The only reason I don't own a Squier CV 60s P bass is that for my personal tastes the necks were a little too thin. Nice necks, just not my preference.
I was bass shopping earlier this year and came upon a Squier CV 50s (single coil) P bass that it was all I could do to walk away from. The only reason I didn't buy it was because I was dead set on scoring a split-coil P bass with a rosewood fingerboard, already having a P with a maple board.
