I just got a 7,000$ (new price) optics assembly from Fleabay (80$, New Old Stock) tossed in a box with one inflated air pillow. Fortunately HP built their interferometers tough. He removed the HP stock shipping box and tossed it into a 12x12x12 box with one air pillow. Not good. The thing is a 2.5 inch cube. So far, no scratches on any of the cube faces, but I sweated until I could test it.
