Need a backpack or sling for D200 + 80-200 2.8, 18-70 + flash

I'm going on a foreign trip and I don't want to carry my big Tamrac bag. I want to take my D200, 80-200 2.8, 18-70, and my flash. Do you know of a bag off hand that would fit these dimensions perfectly. I prefer a backpack or a sling so I can have my hands free.
Thanks
