The Fender Classic '51 Precision Reissue is "crafted in Japan;" the others are "made in Mexico."
I've had two, and the quality has been excellent. The first one I got is the '51, and I fell in love with it. It's the Thump King. I changed out the pickup for a Basslines Quarter Pound single coil, and installed an American Deluxe bridge to replace the 2-saddle original. It drops right in, and has holes drilled for through-stringing. It has Thomastik-Infeld Jazz Flats, which I put on all my basses these days.
The neck is perfect for me. I can't tolerate skinny necks, and this one, while slimmer than the real thing, is nice and chunky. That's a deal breaker for some people.
Finish is even, glossy, and deep. I don't care for the butterscotch color, but you can't hear paint.
About a year later I got the Classic '50s Precision in "fiesta red," installed a Basslines QP split-coil and TI Jazz Flats, and gigged with it every weekend for the next year, until the band I was in broke up. Another great neck, another nice finish I thought was ugly, and the killer P tone. The band refused to let me play anything else, once I showed up at practice with it.
Eventually I used the '50s for trading stock, since I had started concentrating on playing my fretless Precision, and the '51 stays at a friend's house. I go down there and play every week, and he's really in love with it. He has a choice of a Jazz, a late '90s
Gibson Les Paul Standard bass, and a Guild B4N, but they all sit in their cases now.
Things that aren't great: color choice, the vintage 7-1/2" fingerboard radius, the fact that you have to remove the neck to adjust the truss rod (but my two required a total of one tweak). Other things I love: the small vintage frets, overall feel and looks -- apart from the color.
If I were back in a band, and I wanted a fretted bass to play, I'd immediately grab another Classic '50s.
