Ugh the Henle Urtext are so damn expensive (and I cant seem to find them anywhere in China, poor me

)
For the Sonatas Op. 2-22 (Volume I), I have the Konemann Edition. Very good edition, hardcover, you can get them cheap at Paris and elsewhere. They have very good proofing and I love them better than the Henle (which, BTW, are so boring to look at.)
For the Sonatas Op. 26-53 (Volume II), I have the Wiener Urtext (My dad got it cheap in China

Don't you LOVE taking advantage of low Chinese music-book prices lol).
For Sonatas Op. 57-111 (Vollume III), I have the Konemann. FYI, they were published in Budapest a long time ago, so they're very cheap, yet very good and high-quality (no typos anywhere).
