I have to send my MR-88 tuner to Audio Classics for some service. I have the original McIntosh packaging for the tuner. I am probably going to ship it UPS Ground. For those of you who have done this before, would you insure the package for the full replacement value (which I believe is about $5000), partial replacement value, or just have faith that it'll get to Audio Classics okay and not insure the package at all? I will be shipping from South Bend, IN to Vestal, NY...
