samsonite spinner - i have a model that is very light, love it - they are pricey but last forever, if you have a problem - you send them in and they fix or send you the newest model.
i had to send my last one in and got a brand new one (that was super light) in return just a few weeks later.
love them!
same with american tourister - they are made by the same brand / company. we have had to have repairs (same thing)... got a brand new bag in return.
they stand by their bags.
