I don't think Squiers were ever uniformly crap. There were definitely eras and places of manufacture where a Squier would require some fret work, but that's true of Fenders as well. The early Affinities definitely had crap tuners, tho! I think the early MIJ years and China-era Classic Vibes were probably the most consistent, and the least demanding of mods. Ultimately you take a look and you see what you get. I've owned a ton of Squiers, and they've all been useable.
I've bought three used Squiers sight unseen and they've all been ok. #1 is an Indonesian 2011 Vintage Modified Mustang Bass. The luthier who subsequently set it up says it has a mild twist in the neck. The twist is undetectable to me, and the Mustang sounds great and is a great player. #2 is a La Cabronita Telecaster from the mid teens, which is flawless. #3 is a newer Classic Vibe Jazzmaster. It plays and sounds perfect, but when I took off the neck, there was a crack near the truss rod. I put the neck back on and proceeded to not think about it, figuring I have a Strat neck I could eventually put on it if I needed to. It continues to play well and sound good.
I also have an early MIC Classic Vibe Strat, which has been nothing but perfect since I bought it new, and I've owned an early Affinity P-Bass, which had good bones, but needed new hardware and electronics.
In other words, they've ranged from nearly flawless to useable. The worst was a mod platform, some of had mild irregularities that would be unacceptable on more expensive instruments, but didn't interfere with my enjoyment, and some were nearly flawless, and could easily compete with more expensive instruments. The best was a very early Chinese Classic Vibe Strat, which had spectacular vintage-style pickups, which were made for Fender by Tonemonger.
