Where before we used to look at quality and longevity, I'm afraid now luggage restrictions are so strict what counts most now is......weight. Even cheap bags don't fall apart on one use now- you are almost just as likely to have a Samsonite case bricked- if it's your case's turn, it doesn't matter what make it is. I was looking at some really cheap large wheelie type bags yesterday that were extremely light. After a few trips, you can replace them with new ones for still less than the price of a new 'quality' case. With your big trip, every kilogram will count- keep it light. The lady in the shop was telling me that she's just come from Oz and paid 700AUD in excess baggage. A large case was just over 33 Pounds cost, and packed sensibly, the contents give it a lot of its strength.

Strewth- just looked up that case! It's 155 Pounds! Get a cheapie, and if you're not happy, on one of your trips to the Far East, get another cheapie where it's cheap. But that is insane. Not for ordinary working people! And sticky-outy wheels like that are a challenge to loaders! I do walkarounds of aeroplanes whilst they're loaded. You see bags coming off conveyors (up at 747 hold level!), falling off carts, thrown around by loaders. Favourite LHR loaders trick is to drop crew cases if they decide they are too heavy. Stuff quality- go for practical!
