The contax coverings are nothing to write home about either Jim.
I just saw a thread where maybe it was the 2000 (forget the exact model designation) where a couple people were complaining about gearing and other plastic parts.

Like I said I never owned one and haven't been inside one to compare so take the internet advice with a grain.
I got lucky and got a 159 with discolored covering for 35.00 usd so went that direction.
I know the contaxs dont have the best rep in the electrics dept.
