I can (most likely) fix it.

Cost will depend very much on effort, but even the worst jobs thus far have been cheap (for the owner). Minimum is US$50 to poke at it, and that's usually enough to fix it. Max is more like US$100, which I don't think I've had to charge yet.

As you can see, I don't make much for the effort put in, as my motivation is simply to help keep these nice machines purring along.

Cheers
