I'm with David on the extra cases. I do a regular local craigslist check for them - I've picked up a half dozen for $10 - $15 apiece, so my stuff (not the 4x5, just the nikons and rollei's, including several meters, etc) are spread across several bags. I just put together what I want for that day/shoot. I have a great Tenba (my favorite brand) that will hold anything I might want.
