This is a really amazing flash that I bought last year on black friday sale for $350. This year, they have dropped the price even more by $50. It does not seem to go on sale often at all. I checked throughout the year a few times.

I bought this wireless trigger:
to ensure that I can trigger from my camera. The pictures are amazing. The flash has enough power to completely fill up a large room. I bounce off the ceiling in my 12ft high ceilings and usually I can only use about 1/4-1/8th of the full power.
