you have to admit he,s got it all covered ! but still the cheapest so stick with him, by the way best bag for taking on board  i have found is a very thin material bag from Ikea around £4.00 with a family card weighs nothing and fits loads in , easy to cram into the cage of doom but if not careful ! I took over a cafetiere last trip ,and crunch it went as my  bag was jammed into the cage, so weighing might be a bonus LOL ;)
