I've been using a Kirkland (Costco) 22" rollaboard for about three years and it is working great. It has done a dozen or so trans Atlantic trips plus a domestic one or twice a month. Other than some scratches on the plastic guards (from dragging up stairs) it looks brand new. And it came in ugly olive green - I've only seen one other matching bag. Also expandable by a few inches for all those things you pick up on trips.

It is a little heavy, but the newer ones do advertize 30% lighter or something like that. They also have a large (30"?) wheeled checked bag. I noticed they now carry them in ugly brown, ugly light blue and red in addition to the standard black.

I also like Ebags. I've got a Weekender Convertable that is the same size as a rollaboard but holds more since it has no wheels. It does not get as much use, but is very well constructed.
