I have the 24" Baseline Superlight and it's held up quite well. It's been on a few US - Asia flights, inter-Asia flights and numerous CLT - HNL flights. It still looks new except for some wear and tear on the straps but the wheel still roll so smooth!

I was able to get my Superlight on sale online so the cost wasn't too bad. I highly recommend B&R for checked luggage.

I also have a 22" Expendable I use as a carry-on. It's been doing 100k miles a year since 2006 and still looks brand new as well. I'm not sure I would spend the money on the carry-on luggage because I almost never check it and always keep it with me. There's very little chance of it being damaged but the warranty is a nice piece of mind. Again the wheels on the carry-on roll very very smooth which is important to me.
