Messenger style bag, gripped body + 70-200mm

[matseski]

I am going to be studying in Europe in the fall and the last thing I need to purchase before I go is a camera bag. As my kit has been expanding, using my backpack is no longer a practical option. I want something that will hold a gripped body with attached 70-200 f2.8, 17-50 f2.8, flash, Gorillapod Focus tripod with ball head, and some extra memory cards, batteries, filters, sunglasses, etc. It would be really nice if it had a zippered section against my body in which I could keep my passport/wallet. Some water resistance and 'street safe" styling/labeling would be nice as well.

As a student with all the expenses associated with studying abroad, I would like the most economical solution, while still being a bag that I will feel comfortable carrying around thousands of dollars worth of equipment.

So far the least expensive bag that I have found that looks like it will meet all of my desires is the Thinktank Retrospective 20. It looks like a great bag and should last for years to come, but at $170 it is certainly not the most economical bag on the market.

Does anyone know of any other bags that are designed to accommodate the equipment that I am looking to carry in a sleek, fashionable, and functional design for less than $170?

Thanks

Try the Lowepro Classified 160, 1/2 the cost of the bag you were looking at.

You can also get any messenger bag and just put in an insert.

I've tried a lot, but Tenba takes the cake. It is just awesome. Tenba | Photo Laptop Messenger Bags

I've stuffed the large one with a ton of gear. I think the most I had in it was...
Canon 7D, gripped with 70-200mm f/2.8L IS II (attached, collared, hood attached/reversed)
Canon 5D2, gripped with 16-35 f/2.8L II (attached, hood loose) or 100mm f/2.8L IS (attached, collared, hood attached)
Canon 50mm f/1.4 (no hood)
Canon 580 EX II
2 extra camera batteries, and charger
Mini rocket blaster
GorillaPod SLR-Zoom
A small umbrella (for rain)
1.5 TB Harddrive
Gaffers tape
15" laptop, power adapter
iPhone
iPod
Memory (CF cards, thumb drives)
Business cards
Flashlight (2-AA size)
Passport, papers, pens, highlighter, ear phones, Visine, gum, and other small things.

It's quick-access zip-top allows for better privacy too. I don't need to show the whole world what's inside the bag when I take a camera out.
