March 5, 201511 yr I have 2 used Inon S-2000 strobes for sale. One strobe shows more wear than the other but both work as good as new. The strobe with more wear shows a "touch" of surface corrosion on the battery terminals on the lid. It's purely cosmetic and does not hamper function but wanted to mention it. Newer strobe: $350 Older strobe: $300 Take them both for $625 shipped
