Any advice on a camera bag?

[birder_herper]

Hello all,

I'm looking for a camera bag to carry a few of my items when I go out shooting. Here's a list of what I'd like to fit in this bag:

Canon 40D

Canon 60mm USM macro (smallish lens)
Sigma 180mm EX HSM macro (medium lens)
Canon 10-22mm (small-medium lens)
Canon 18-55mm IS (small lens)

Few Compact Flash Cards, extra battery or two.

Any suggestions?
I was thinking something like this might work:

My favorite bag is the ThinkTank rotation 360. www.rotation360.com. Medium sized backpack. Its high end features come with a high price tag, but more than worth it for me.

That case looks great for the price. However, I personally will never buy another camera bag without looking at it in person again. You just can't get a real feel for how things will fit and the comfort without actually putting your hands on it.

Check out the following site for more ideas though:

I got the lowe pro flipside 300, its comfy, not too flashy (if you get the black on black) and it is secure since the opening is facing your back...also it has a tripod mount and water bottle pouch for trekking... it fits all of my gear including filters, remote, filters and cleaning kit.

+1 for the Lowepro Flipside 300. It's a terrific bag, comfortable, secure and you can get your gear in and out of it without taking it off. I love mine.
