Maybe I missed something in this thread, but you never said what the problem is?

Leave everything alone till you see where the problems are coming from. Light seals, that little edge lever that engages the counter mechanism, the roller that sneses the film that tranfers that info to the counter to meter a frame.. so many possable places to find the same cause of your problem... so lets isolate it n cure it?

How handy are you? Perhaps you can do your own repairs with a little guidance? If it is broke now.. the worst that will happen it will still be broke after you try fixing it.. deal?

Shipping to Canada is off the charts lately.. I have no idea why. Are there any local repair shops in your area?.. maybe someone that is a bit more handy than you willing to help?
