I'd like a larger case like that Sam's club model but they don't seem to be available anymore. I picked up a couple of the HF cases... the medium and large model. I set up the medium for a sat' phone:

Seems pretty durable - not reinforced nylon like some really strong cases but even most of Pelican has switched over to reinforced poly ethylenes. The HF case pluck foam works well and it has a good gasket on it. The release valve seems a bit cheap but for $30 (less when on sale or using a super coupon) it's a good buy. I'm re-packing everything in preparation for a 2 week trip this summer that may involve a few of these or the larger ones.
I'm also using Home Depot's Rigid line of tool boxes that connect to one another for storage, etc. They are pretty strong (you can stand on them - I'm 250lbs) - they also have a pretty good gasket in them. The smaller ones lock onto the wheeled box.
