I had a 6 piece luggage set made with different size bags for a grant total of $70.00! The one lag was an expandable on wheels. It would zip down to 18 inches high and unzip to 38 inches tall, 24 wide and 15 inches front to back. You could pack an insane amount of stuff in that thing. The other 4 was a gymbag with racquetball racquet holder and three different sizes of duffel bags sort of like what you put up first.
