a good quality...airline carry-on bag

Recommendation here: Several years ago I bought one of the Eagle Creek Tarmac series of bags because I was flying a lot. They are expensive (less than $300), but have a lifetime warranty including damage done by an airline (every other bag I saw excluded damage done by airlines). They are very tough, well designed, visually distinctive and just small enough to fit into most airlines carry-on maximum size. Last year I bought some packing cube nock-offs and that has also made packing and unpacking more enjoyable.
