I have brought lenses and cameras from KEH. I look on the website first and then call them. They get the equipment from off the shelf and describe it to me. One Hasselblad lenses I had questions about, the sales person sent out to be checked and apolagized that it would take a day to get the answer! When I called the next day and the lenses was checked out I brought the EX lens. Bel Air Camera and Samys both said that then lens was in mint condition.
