I have two DS-125 strobes, and a total of four NiMH battery packs, with two chargers (one is the Ikelite charger, one is not). Ball mounts on the strobes. I just used them on dives in the Sea of Cortez, and everything works well. $650 takes it all, shipped in the US. I also have two Ikelite optical-to-Ikelite converters to allow fiber-optic connection to the camera; the converters are priced at $60 each, or $100 for the pair if purchased with the strobes.
