Power Pack for Camera and Flash

[lorrir]

I have a Canon 30D and a 580EX Speedlight Flash. I am in desperate need for a power pack. I'm tired of charging AA Batteries. :x

Anyone have any suggestions? I heard Sunpack has a good system.

Quantum with the proper cable are the leaders in that arena. Unfortunately, I do not have any direct experience.

I modified my 550EX to connect to a battery pack that I hang on my belt. The battery pack has 4 D-Cell rechargables and last significantly longer than the AAs. However, the cycle time will not be any faster than fully charged AAs since it is not connected to the flash's high voltage terminal.
