I am interested in what people have to suggest, as well. I need a rollaboard that has a place to hang a suit and fold it up in the lid. I recently bought a Samsonite, hard side on the base and sides, fabric on the top. I am relatively pleased with it, but don't like the two straps that bisect the outside pocket area. It's fiddly to have to snap the straps, and I lose some storage space. Also, none of the three outside pockets are large enough to hold files.
A colleague has a very expensive Hartman (>$400)with which he is extremely happy. I'd prefer to find something <$200. (My Samsonite was $180.)
