Bag recommendations for small kit: 60D + 35MM + 70-200 + flash (maybe)

Hello all:

I'm finally returning to photography after a 1-2 year hiatus. 60D should be arriving any day. I have a 35mm f/2 right now and plan on getting a 70-200 relatively soon. I don't foresee many more purchases beyond that, but I'll probably get a flash at some point.

I'm looking for a bag that can hold my limited gear plus a little extra space for phone/keys/wallet/memo​ry cards/etc.

I think a backpack design would be best for both comfort and maneuverability when not using the camera.

Budget: lower to mid-range

Thank you in advance!

Thanks for the suggestions, guys. This will give me a good starting point. I think I have to take a look at some in-person.

I use a lowepro fastpack 200, an excellent bag for all my kit.
