Grading Used Lps: What to look for?


Hey folks...my used options in my area include stores that use a fair,good, and fine grading system for Lps...however... since grading is highly subjective...there seems to be grave inconsistencies...I often find LPs with minor hair-line scratches cleaner sounding than mint Lps with some surface particles(even after cleaning)...any suggestions? For high demand used artists...stones,floyd,etc...the grading system is pretty forgiving and the price not surprisingly inflated...sometimes you really dont know how an Lp will sound still you bring it home...is this just par for the course for going used? ALso have Santana Abraxas which is warped and nicked...but is quiet as a church mouse...

Other than the used vinyl I have purchased here on audiogon (they rate very good and, to me, it's mint), all I have purchased (used) has been a disapointment. My (new) rule is only audiophiles know how to grade vinyl.
Best you can hope to do is visually grade them, clean the heck out of them before you play them and hope for the best. If you've got a good seller, he/she might let you play them in the store before you buy.
What ever you find that you don't like, please send them on to me. I'm finding fewer and fewer that I can't clean up.

Maybe because I'm better at screening them? I don't know. Still, after several years of buying used vinyl I don't find any difference in the number of records I can recover.
