Oh that's terrible H, I feel for you! Hopefully it's just a cheap fix so you can be back in action soon. We are eagerly awaiting the completion of your Rho mosaic, looks fabulous so far
If it does turn out to cost you $3k I'd be looking seriously at getting a newer camera instead, for example one from the QSI range with inbuilt OAG (totally unbiased opinion of course
).
