This pack holds 6 AA and with 4 in your flash you can shoot all day and your recycle time is much faster.
I got this from B&H about 6 months ago and shot 8 weddings with it then got SB-900's.
The new model is on its way and I don't have SB-800's any more.
It is used but never abused... few faint marks but nothing major.
Includes box and protective case (I just put it in my shirt pocket, thats why it has a few faint marks).
These are $149.99 plus shipping from B&H
This one is $125 to your door.
