I've just got the hudy bag from MB, it's awesome..
Drawers are not cardboard, they look to be the same plastic as the fastrax and the quality is exceptional.
If you can get an older fastrax bag, they have a more durable handle, it's the later extruded aluminium ones that seem to have the problem.
Oh, be warned the biggest hudy bag is massive... Wouldn't fit in my v50 estate boot! Gutted as it's like the Cadillac of rc boxes
