PelicanI’ve been using the Pelican PCS172 soft-sided briefcase for a year or so. It’s the first wheeled briefcase I’ve found that can simultaneously hold my laptop, my tiny projector, my Canon 20D digital SLR camera, five lenses (including my 100-400mm) and all the accessories associated with all that stuff. When packed properly it will fit under many airline seats (although many of the newer planes have video in the headrest which also adds a box under the seat which forces me to put this bag in the overhead bin).
