It's amusing about the Reader's Digest sets. If you want to collect those, even now it's easy to find mint condition sets for practically no money at secondhand record and book stores, library sales, flea markets, and of course online. It's as though people subscribed to them and rarely, sometimes never, played them. I had about a dozen such sets before the Purge, and they were practically audiophile grade vinyl -- partly due to the above theory, but they're also known for excellent pressing and sound quality, having been produced by RCA in their prime. Great attention was given to their design and manufacture.
