i currently have the nikon SB28 and i want to get another SB28. i want to have the one flash as a off camera (tripod) and the other on a sync cable to my camera. how do i accomplish this even tho they're 2 different worlds, i have the canon Xti btw. this is what i think. i'm getting the cactus triggers on ebay. one transmitter and 2 recievers. ok i see that the transmitter got the socket for the 1-pin plug to go in. will i be able to connect this to the sb28 and at the same time have the other flash to sync wirelessly??
