Experience with Amazon Warehouse
I've purchased 4 lenses through Amazon (both new and used):
50mm f/1.4, 16-35mm f/2.8, 70-200mm f/2.8 IS II, MP-E 65mm f/2.8 macro
Everything arrived in new (or very nearly new) condition, either in original packaging, or in more than sufficient packaging to keep away any damage.
