I've been trying to find a compact messenger-style bag that I can use to carry my 12" Powerbook, Sony A100 with a lens attached and maybe one or two other lenses or a flash. I'd like to have something small, but have been having trouble- most messenger bags made for laptop + camera temp to be massive and would fit a 17" MBP. Something like the Tamrac Adventure 4 is around the size I'd like, but it would have to be an inch or so thicker to fit the PB. Something like the Lowepro Stealth Reporter 550, on the other hand, is too thick and seems uncomfortable. Do any of you know if there's a happy middle ground somewhere? I defintely don't want a backpack and I can't say I find the sling-style bags particularly appealing...do any of you have any suggestions?
