I was trying to decide between the EZYBox by Lasolite and the Westcott Mini Apollo. That's when I stumbled upon the Cheetah QBox 24 while reading some forums:
http://www.cheetahstand.com/servlet/the ... -24/DetailThe reason why I went with the Cheetah is well as you know, the EZYBox is very expensive for what you are getting, and the Appollo was a little too small for my tastes at 16" by 16". The Cheetah is 24" by 24" plus it comes with a grid and round mask all for under $120.
I purchased mine with the shoe-mount bracket, but they also have a bracket for the AlienBees($18) which I'm about to purchase pretty soon. I think that for color accuracy the Westcott Mini Apollo would be your best bet. I found the Cheetah a little warm, but I was able to compensate by turning down the color temparature on my camera by a couple of notches. After doing that, the light is absolutely great ! Almost like a spotlight, but much, much softer.
