Derailleur Ultra FS Pro.

When all was said and done, this cost me $60.00 (mostly shipping from Canada to US). Biktrix customer support was very good though.
Thanks Biktrix

Super fast service

I was surprised that derailleurs are not the same even from the same brand. The only place I could find it is at Biktrix and it was delivered quickly and works well.
