I'm not using this Nikon SB-105, which has a fairly significant problem: a broken connector pin. I'm the idiot that tried to force a connection. The strobe powers up, has a good o-ring, and fires with the cord properly connected in manual mode. It also works as a slave. $1 plus shipping to your location. 5 lb 4 oz box, 13x8.5x8 USPS preferred
