Hey all - I have never bought a Quad LP or equipment, so I have no experience in pricing. I saw a copy of the quad LP of Jeff Beck's Blow by Blow in a Thrift store yesterday. It didn't have the proper cover, just a plain white one. The record itself looked in very good condition, but then again I don't know what to look for in a Quad LP. The price was $8. I'm not interested in purchasing, but if anyone here is I can go look for it again.
