thanks all!
I did some research and decided on the Briggs and Riley Montauk bag. Conveniently, I was in Detroit for work this week, had dinner and went to the mall with my Dad ( who lives in Detroit, he doesn't chaperone my trips

). He got it for me as a B Day present and so far I really like it ( 2 days and so far so good)!
Thanks again for the advice.
