I often mention that "several" Amazon sellers have a certain item available, and have been asked if I could be more specific. First let me say that in nearly 100 transactions in the past few years I've had no problem with any of them for either new or used classical discs. Any of the used items described as "very good" or better have had essentially perfect disc surfaces.
For the Bartok collection suggested above I can recommend the one I've dealt with most frequently because of excellent service, i.e., "blowitoutahere" who's offering the 2-disc set for $7.24.
I'll also list those I've had multiple dealings with: Classical Music Superstore; importcds; newbury_comics; mbischel3; MovieMars.
