Read the descriptions carefully -- it's accurate. You won't get a pristine lens unless it's rated that way, but at least they optically check their lenses. I bought a 100-400 from them last year during the black friday sale. It was in great optical shape, but some of the paint had come off from the tripod ring, where renters had scuffed it up mounting/unmounting it. Do your homework so you know what you're getting for your money, and if the price is right, then go for it.
