Does anyone know of a good clock (not watch) shop, or where to buy quality clock "engines."

I have a freind that owns a clock watch repair shop, however I do feel that the inner workings are not for sle but the repair is obviously available.
While i applaud those who can repair their own timepieces, in this country the cost of paying someone to do it is so minimal that getting them to do it is I pesonally feel the best option, it also means you donot have to try to explain what you want exactly.

and where has your freind his chop?
