I'm about to pull the trigger on some studio lighting. I need the most bang for my buck! My thoughts: 2 AB 800's 2 13' heavy duty stands 2 48" umbrellas. The area that I'm going to take pictures in will be large enough so I won't have to worry about light spill, relections..etc Radio/Transmitter combo I think I'm going to order it tonight to get a jumpstart on it. Am I missing something? Am I making a BIG mistake?
