All of my co-workers have Tumi but thus far, my Samsonite Xenon shock absorber looks just as good, holds up just as well, and is just as function as the Tumi at a price of around $50.00.
After 9 months of flying 2x a week, the bag looks brand new, the zippers are prefect, there are no tears and its perfect (the same as my co-workers Tumi's).
Not knocking the Tumi........time wil tell if the sammi holds up as well but after around 50+ trips, being in like new condition is saying something.
Of course, i usually get upgraded to 1st class so im not as hard on bags as some

(but i do carry a lot of weight in it).
