Thanks for the Crumpler thought. I've been doing a bit of research since my original post and the leading candidates are:
Crumpler Million Dollar Home (something in the 5-7 million range)
Thank Tank Urban Disguise 30 or 35
LowePro Slingshot 200
Tamrac Velocity 7x or 8x
Anybody out there have strong feelings - positive or negative - about any of the above.
