+1 for ThinkTank Products. They do look pretty darn sexy.... and by that I mean clean and sleek, and not too obvious for would be thieves.
I have 3 different Think Tank setups. The Airport Takeoff to hold everything when traveling, The Sling-O-Matic 10 for casual shooting conditions, and a Pro Speed belt w/Pixel Racing Harness+Digital Holster+Modular set for wedding shoots.
