another vote for tumi here. incredible quality and pockets and zippers and doodads in just the places you want them.
re: the outlets... cordelli is absolutley right... if you buy a discounted bag, it does not come with the lifetime warranty. however, they often feature1st quality bags in discontinued colors. i bought two bags for my girlfriend last year; she prefered the green - which was just fine with me - as it saved me a lot of money.
i chose identical bags in black for me and they were several hundred dollars more. the carry-on is particularly expensive at almost $400! (compared to only $100 or so more for a much larger bag.)
