I'd call an independent repair facility for a second opinion, or quote for diagnosis. I couldn't bring myself to pay $450 to repair those old 8x30 SLC.
Thank you for the suggestion. I didn't realize independent repair facilities existed . Do you have any you would recommend?
Unfortunately not, in terms of firsthand experience.
However, I bet you'll get some good advice with a new post asking for suggestions. And I'd be tempted to call Cory Suddarth as I've heard good things about his work.
