Valse impromptu difficulty

[maxiboot]

I would like to play liszt's Valse Impromptu. I am an intermidiate player (I have played for three years). My only experience with liszt his his liebestraume no 3 which i can play fairly well. How does the valse impromptu compare to liebestraum no 3 in terms of difficulty? I understand that it is a fairly difficult piece and I dont expect to be able to play it very soon, but what are some good pieces to work up towards that level?
