Find me Shimano XT RD-M770 "Rapid Rise"

[Revotseel]

Help! Broke XT rear derailleur.
I have the integrated shifters (ca. 2009), so I need this older XT version, not wanting to shell out for a full upgrade just yet. Prefer medium cage, but I'm becoming less and less picky.
Found one in the UK, but these blokes are not responsive to my order placed two days ago.
Where else can I get one of these?
Currently in Boulder, CO.

Have a shop check with Euro-Asia Distributors. They seem to specialize in old stuff (yeah, these qualify now) and they do list Rapid-Rise.
