i've had my substance original trolleyboxbag for over 2 years now and it's only just starting to look a little knackered and this baby has been everywhere and on at least 150 flights. They are only about £90 and the handle is a solid as anything and I even lift the thing up flights of stairs with the handle and it's ok. Trolley bags are the way to go as osteopath will say you only have 1 back so look after it. The flight case boxes are so terrible and everyone will tell you after walking 50 yards with major bruising and sore arms.
