Can report that I bought the the Delsey Wagram 2-Wheel Garment Carry Case and took it for a week business trip in Asia. Very happy with it overall.
Pros: Keeps suits in good condition. You have to fold the arms in, so they end up a little wrinkled, but what wrinkles there were fell out after hanging the suit up overnight. Good capacity for other things - enough for two large packing cubes, toiletry bag and a pair of shoes. Easily managed a week business trip with this and a smaller personal item bag. The construction of the case, handle and wheels is very good quality. The wheels roll incredibly smoothly.
Cons: It can be tricky zipping it up around the corners. The extension handle has trouble extending if the bag is too stuffed. There is no external pocket for a laptop. The small external pocket on the front is incredibly tight. The small pocket on the side is more useful.
