Hoffy, Charles has always been a good bet - even if the camera needs parts; have been using him for years - first met him when I was an assistant many (many!!) years ago when I had to drop off some 'Blad gear for one of the photographers I was working with at the time.
He can get swamped, but I've never had any problems - only camera he wasn't able to help with was my old Junior 620, as he couldn't get any parts for it. (Same result from another guy L&P recommended - couldn't get parts for the winder, so couldn't repair for me either.)
Can't vouch for any interstate, as haven't used. HTH
