Thanks to Akrubenstein for starting this poll! We've contacted the vendor on your behalf and they've made the Kelty Strike 37 Tactical Backpack available.
Update time!
Spoke with Kelty, they're interested in working with the community. That said, the Raven 41 isn't the best choice given the production lead time is nearly 8 weeks. Instead, the proposed the Stricker 37 Backpack, http://www.kelty.com/showproduct.aspx?ProductID=263&SEName=strike-37&category=backpacks
Let me know what you think. Sample's on the way to our office and it should be ready for listing soon if everything checks out.
Will update again when more information is available.
Just added the Tom Bihn Brain Bag to the vote, it's a great bag. But I wasn't able to add a picture. Drag & Drop didn't work for any browser I have (Chrome, Firefox, IE, all on Win XP). Could somebody add a product image?
Also, there ought to be an alternative to drag & drop (like the click-button I see below this entry field).
