I have Nikon D5100 and it lacks wireless flash capability. But i want to use flashlights off the camera. I have googled for various options including cactus and yongnuo products for wireless remotes for controlling flashes but didn't understand which one is better. I think SU-800 will do the trick but since it is expensive i need some inexpensive alternative mentioned above(cactus, yongnuo etc) .Also recommend flash and remote best suited.My budget is 400$( may be bit more) .
