Thanks, MacGirl, for the Timbuk2 Small Messg. ($60) + Tenba insert ($20) photo and description.
I've been spending a good deal of time this week trying to find a messenger camera bag to take my K10D and lenses on vacation. I wanted a bag that didn't look too much like a camera bag, was weather resistant and that could serve other purposes given the cost. I went and tried on the small Timbuk2 and it felt pretty good and not too wide or deep. Normally, as a woman, carrying a bag cross body is a bit uncomfortable, but that was so with the Timbukt2.
My choice was between the Timbuk2/Tenba and the Tamrac Messenger 4, they are very similar in size and price. While the top handle and external pockets on the Tamrac were pluses, the versatility of the Timbuk2 won out. My husband thought he would break the clasp on Tamrac even though I liked it. Also, the quick release adjustment on the bag strap of the Timbuk2 makes passing the bag off to my (foot taller) husband a lot easier
