Transcendental etudes score request

[pianogod]

I am looking for an excellent Liszt edition of the complete transcendental etudes. I know there is a russian version out there and I want to know if it has a preface. I also posses the first edition and the Busoni edition. If any one has a very good urtext edition of these pieces I'd appreciate it. I need the etudes for research since I'm making my own Urtext edition and want to compare what is out there.
