"Many of my "not" Golden-era pressings from the mid-70s through late-80s also lived up to expectations when I got them home. Many more did not, and that's why I ended up jumping on the CD bandwagon with a Sony CDP-101 in 1983."
For me, those are some of the best records I own. Just regular ones that were lightly used, and just sitting on someone shelf and just listed the whole lot on ebay.
Getting back to your original question, the records may not be warped from the factory. It could have been neglect from some point after they left. I don't know what kind of TT you have, but my VPI has a screw on clamp that works very well. If its something you can get for yours, I would say its definitely worth the money.
