NW broke my bag and gave me an Atlantic brand. It's ok. It's better than the ones at WalMart.
My philosophy is not to buy expensive bags for check in but if you carry it on, you can probably take good care of it. Make sure it rolls well and doesn't wobble (easy to wobble if the wheels are too close, an error in the earlier days of rollerbags).
The Atlantic brand is heavy so it's bad for certain airlines, like Qantas, who demand light carryons.
