I traded in my old Nikon and two lenses for a newer model Nikon and a Tamron 18-400mm lens. I chose one that was described as excellent and figured it would be good to use right away. While the camera was in good shape, the lens needed to be sent to Tamron for service. Since warranty doesn't travel with the item, I had to spend over $200 (discounted price) to have the lens serviced with Tamron. It certainly would have been cheaper to buy the lens new. I contacted customer service about this issue over two weeks ago and still have not gotten any response. At this point, I would not recommend using this company, unless you just want to sell your gear and are ok with waiting a sweet while for any kind of response.
