Several years ago, I bought a nested pair of Ricardo of Hollywood suitcases at Costco. There's a big one that, when expanded, is just shy of the maximum permissible checked bag (without paying extra)*. The smaller one is carry-on-able. They have carbon-fiber shells. They are what are called "spinners" and they roll and move extremely well. I've just never had a suitcase that was so effortless to move and handle. The quality of the shell and zippers, wheels, handles, etc. is good. I've probably flown 25 or so trips with the big one now and it's holding up quite well. It still looks great. I don't use the small one a lot; I'm a bit of an over-packer and that little one is maybe enough for a weekend for me... assuming that I don't need a suit. One thing I like about these two is that they don't have a lot of over-thought internal "organizing features" that tend to be variously non-functional, useless, or quickly-broken. I seem to recall paying about $120 for the pair. I'm very pleased.
If you're a Costco member, take a look at what they've got. And, otherwise, I would encourage you to look at Ricardo of Hollywood.
* Keep in mind that airlines are often being very rigorous about weight limits these days. So, a big suitcase isn't always a good idea. And activating the "expansion" zipper feature can be an easy way to end up paying an excess baggage fee.
Also, Costco got into a bit of hot water with customers a few years ago when they sold a suitcase that, when you opened the "expansion" zipper, went over the maximum airline size thus forcing an oversized bag fee. The suitcase in question was, when not expanded, just about exactly the maximum size and some customers complained about being charged oversize fees simply because the ticket agent did a sloppy job of measuring. The large Ricardo suitcase I have remains comfortably below maximum permitted size even when expanded.
