All of the CD's in this link are under the Amadis label (branch of Naxos) and are $2.98 per CD! I mean, I bought almost all of these, able to hear some actually well performed piano pieces and works that I've never heard before. For instance, Ethella Chuprik leads the Amadis piano recording banner, and has played one of the best versions of Liszt's Mephisto Waltz No. 1 I've ever heard. All the big guys like Bolet, Brendel and Arrau aren't worth it after her performance. She also does some excellent Beethoven renditions of PS 17, 26 and 31.
Additionally, the Amadis label gives rare works from Vivaldi, Rachmaninoff, Mozart, and Bach. I mean, I even got to hear Rubinstein Piano Concerto's that I had never heard before. The actual recording quality is just fine and I've never regarded them negatively. There may be some disagreements over interpretations, but overall, what you get for the extraordinary low price is just unbeatable.
