Thanks for your input. I'm going to open up the 'for parts' body and work out the path of the flash wire etc so see if its 'user servicable' by me. Will post an update whenever I do that. I don't have precision screwdrivers right now, and can do without the flash until I get some.

The OM10 seems like a decent camera to me at present, seems I would change my mind if I had it side by side with a single digit model. In the future I may consider buying one of the pro line, but as this is my initial foray into SLRs I will wait a while and see whether this would make a sensible investment for me.
