grislybutter and thecarpathian are willing to buy LPs in bunches at low per issue cost and apparently are prepared to find many of such LPs to be utterly unplayable. That’s another valid approach, I guess. I once spent an entire afternoon looking at LPs in a Goodwill. Some had no inner sleeve (a very bad sign because the cardboard cover will itself damage the playing surface), many more had outright gouges in the playing surface, gross dirt, etc. I guess those guys have more patience than I but I would rather pay $5 (for mono) to $15 for a single LP that passes the eye test and contains music I know I want to hear than to pay the same amount of money for several miscellaneous LPs among which I will be lucky to find a single gem. I don’t do estate sales unless I know the guy who died to have been a fastidious collector. Nor do I do eBay unless I have confidence in the seller. Thrift stores like Goodwill.... Stay away. But that is just my opinion. We have one son who lives in Tokyo. Tokyo has superb used LP stores, and the Japanese apparently take amazing care of their LPs. Funnily also, the prices are highest on US pressed originals, compared to Japanese reissues of say Verve, Polydor, etc. Yet the Japanese reissues are often superior to the originals or at least as good. The store I go to once a year rates each LP on an A, B, C scale. Even the B-rated LPs are in superb condition. I don’t even bother to inspect their A rated used LPs, because I know they will be perfect. They also dramatically devalue mono LPs, many of which I find to sound wonderful.
