I just bought the Airport Airstream from Think Tank Photo. I've used it for one wedding and realized I probably should have bought the bigger one. This case does fit a good bit of stuff. Right now I have two 5D w/grips, 70-200, 28-70, 14-70, 85, video light, two 580ex flashes, and batteries and cards with space to spare for smaller things. I do however have more crap that needs a home without me having to take two bags.
I've only had this bag for a week or so. I paid $289 plus shipping. I'll sell it for $250 plus shipping.
Here's a link to the website. http://www.thinktankphoto.com/ttp_product_ArprtAStrm.php
