I had one of the B and W until recently but was not too impressed with it so sold it..Soon after I found an enormous Antler suitcase which my Brompton fits straight into..cost £3 in a charity shop. If you take your time you will find a suitable suitcase in a charity shop for next to nothing. I have three Samsonite suitcases bought in charity shops for my Bike Friday or old Dahon designed folder..Cost at the most £5.
