I've got some 35mm SLR equipment I want to sell to finance some new digital equipment. I've gotten similar verbal quotes (based on descriptions, but not inspections of the actual gear) from KEH and Adorama. Which one is more likely to give me closer to the verbal quote? I'm concerned about getting a high sight-unseen estimate to entice me to send the equipment and then having it knocked down. I'd prefer to deal with whomever is least likely to do this.
