STaL, I imagine you'd be the guy to nab them up in the thrifts. If you find one, great, if not I'll have fun digging for one. I very rarely listen to classical, so I usually pass right over them.
Cleaned my Previn twice today. More listenable, but still a bunch of surface scratches. I was at Jerry's yesterday and could not find a single copy. First time I was back in the Classical section and the classical guy wasn't there.
I've heard the Mehta/LA and Steinberg/Boston are two great recordings to look for.
