Unfortunately that's an outdated list, Gord the owner of Commercial Camera passed on a few years back. I'm in the same boat with a Black OM-2n with a jumpy meter, been meaning to send it down to Camtech but never quite get around to it.
"Life moves pretty fast, if you don't stop and look around once and a while, you might just miss it."
Uncle Bill, the jumpy meter can be caused by corrosion on the battery contact where the contact is soldered to a copper wire or the contacts in the body may have corrosion on them. Also the current 1.5volt batteries available are not suitable for the OM-1. It is easy to adapt the circuit to 1.5 v. battery.
Camtech in Hamilton Ontario (not US) repairs and services in the store. I hear they have a good rep and know Olympus well.
I have not used them yet but likely will when some service is necessary. Give them a shout and see what they say- can't hurt.
John at Camtech does excellent work and his prices are competitive. But be advised that he has never been fast, and now that he is working "part time" the situation has gone down hill from there. I just got my OM-2 back from him and it took 4-1/2 months, door to door. So if you want to take some Xmas pictures, you'd better send the camera off to him now.
We are lucky to have folks like him around to take care of these cameras, but you should be be aware of all the factors when making a decision.
