The Samsonite Oyster though no longer produced by them it THE suitcase of choice - no contest. 8 years and going strong, beautifully worn and easily customised to be unique to you.
Top tip: Samsonite recently bought out American Tourister and moved the Oyster range to them because they are the so-called budget brand. The oytser is a classic design and very durable. I wouldn't even bother looking at anything else.
Samsonite replaced the Oyster with the "Flite" series. Both the OYster and the FLite are currently used by KLM as the standard issue Crew luggage - I believe.
