took the wheel & derailleur down to our LBS. owner says go get the bike & I'll set you up while you wait. not kidding you. an hour later & $90 I'm good as new. told him he robbed me of my street cred by fixing my bike for me. he just smiled & said but now he has piece of mind
he had what looked like a no-name unit in a drawer out back
left the spoke & just tweaked a few spokes
left the cable just trimmed it & shortened some excess cable at the top & replaced the small section of housing at the derailleur
also he was able to tweak the alignment of the new unit (incl hanger) which I think was his main interest. the old hanger looked fine but his replacement had a hanger attached, so ...
of course we had to listen to ea. others stories, but it's all time well spent.
