The Helmet looks really good. Altough its not my favorite Vader, im pretty sure efx will go for an ESB (maybe RotJ) too. Heard that the ANH Version is pretty much sold out everywhere and thats just the pre-sale. Hopefully someone will post a picture in a complete Vader Suit wearing this Beauty.
Regards Lars
It's still available at a number of places:
