BH has 2 different prices for imported and USA models of this flash unit Not much of a difference 12.00 thats it. My question is does it matter? Are the directions in a foreign language? I don't get it. I'm planning on buying a couple of external units to mount on tripods.. I dont know if this is the way to go.. I don't want to lug around heavy lighting equipment. Should I wait and buy lighting equipment or should I use external flashed on a tripod. This will be used for weddings mostly. Any advice would be appreciated.
