I currently have two 580 EXII's, I am thinking about getting a few third party flashes for studio use (off camera). I have done a bit of reading and have found a few but still am not sure. I hope some of your POTNers can help. I've read a bit on the Vivitar 285HV, but still want a third opinion. What about Sunpak flashes? If you were to buy 4 flashes and your budget was under $200 per flash which flash would you get? I beleive the 285HV is only $100. Anyways thanks for your time and your help!!
