I have used Adorama extensively with never a problem. I have bought new photography gear and used gear. Every experience has been outstanding. The 30 day return policy is a huge bonus when buying used gear. I have found the ratings on used equipment to be at least as good as it states, usually better. I outfitted almost my whole studio through them and they have always been helpful. I literally an not say enough good about them. After spending tens of thousands through them, I can honestly say I am very comfortable using their services.
