Which is the point I made a couple of days ago! As I said when you first bought it, I doubt it will be a £60 repair, from what I've read it's got around 1,850 parts in it and you're dealing with 1980s microprocessors and old circuit boards. Consequently, I'd be looking for an experienced repairer of cameras of that vintage, so they are familiar with the camera and know what they are doing and looking for (which should save diagnostic and repair time, which
you'll be paying for!).
Based on previous experience, quotes received and work done, I think £110 for repair and full test, calibration and service on a camera like that sounds like a fair price. From what you've said you only have about a week left to get it for that price though, so perhaps that should focus your attention? To put things in perspective, I was quoted around £120 for a repair on an early 2000s canon EF (non L) IS lens by one of the mainstream repairers a couple of years ago (I kept it for spares and bought a used one for £100 instead), but if they can charge that and get work repairing and servicing modern kit then why should they take your camera repair and service on for £60?
Will the camera be worth the combined purchase and repair price? Possibly not/perhaps on a good day. Is what we do about the price of the camera though, and what was the reason you bought it in the first place? Perhaps weigh that up and see if the
benefit of the expenditure is worth it to
you. If not, then perhaps get rid.
If you're not careful then I can see the camera being hawked around in an attempt to get a cheaper quote (which might be chasing rainbows), then the original place being too busy to take on any new work when you finally go back to them, then you'll end up selling the thing for what you paid for it after wasting hours of your time. Three sayings I've picked up from some wise old folk over the years; 'penny wise but pound foolish' , ' first loss is often best' and 'If something is preying on your mind then take two doses of bugger it'! I often find the answer lies somewhere between the three... but sometimes this only becomes apparent after the event!
Hope this is useful and you make the right choice for your circumstances.
