I would suggest you get Chopin Etudes Paderewski Edition instead, it's the best Urtext Edition out there now, though rather difficult to find and the binding quality rather sucky ( you have to rebind the book ). For Beethoven pieces I would suggest getting Henle Urtext edition, the best Urtext edition for many classical composers, Wiener Urtext is not a bad selection also.
I would suggest you skip on the Associated Board Edition, and get the editions i suggest. You can definitiely find them on your local music score shop, failing which you can fly them in through the shop, most score shops do provide this service.
