I'm interested in the 18-135mm lens, and willing to buy a used one. It's currently on sale, but the ebay prices are considerably lower. I see sellers selling a "new" one as low as $550 with a white box (I'm assuming it was a part of a kit and they put it in another box)
Question is, do you recommend ebay or is it sketchy gray market mostly? I'm looking at US listings ONLY
