Sea & Sea YS-110a strobe is like new in appearance and function. It was bought new and used less than 12 times on one dive trip. There are no scratches on the case that I can see. The strobe comes with a neoprene protective cover that was always used except when stored. Also included are the fiber optic cable and diffuser. You would be hard pressed to find a used strobe in better condition. $525.00
