I don't know if I can take them on the plane with me though...any thoughts?
I took an ET2 tonearm on a plane with me about 5 years ago. They opened the box, looked at it, looked at me very suspiciously, and said, "what is it?" I told them what it was, they closed the box, and kindly gave it back to me to carry on.
I also carried an MC-225 (McIntosh tube amp) on a plane, also about 5 years ago. It was in a really shady looking cardboard box with duct tape ALL over it and they never even opened it. I guess it looked too low tech in the X-ray to even worry about!
