I've done pretty extensive international travel over this time, going to Europe, Asia and Central America for business. Had one issue with stitching coming out on my computer bag, they have a great warranty and repaired it for free. I did tend to overload the bag and it was really heavy causing the shoulder strap attach points to fail. You can get some good deals at ebags.com and luggage.com.
Also as a side note TravelPro seems to be the luggage of choice for most US based flight crews.
