I just received my new Travelers Choice Techno bag and it's exactly what I've been looking for. The only reason I haven't gone for 5 stars is that I haven't yet traveled with the bag, but I'm expecting to problems. It's sturdy, rolls beautifully and has all the features I've been looking for, especially the back strap that allows you to hook on to a small rolling suitcase. Thanks, Overstock! Another homerun!
