I like that you put Butt on the list, he is a great keeper, probably the most underrated keeper in the game, but barthez, dudek, rustu, and lehman aren't what I'd call "super" In place of them I would put: Canizares, Friedel, Van der Sar, and Peruzzi.
Here's my list (based on CURRENT performances):
1. Edwin Zoetebier (Feyenoord)
2. Gianluigi Buffon (Juventus)
3. Iker Casillas (Real Madrid)
4. Edwin van der Sar (Fulham)
5. Maarten Stekelenburg (Ajax) - Arguably the best YOUNG keeper at the moment!
