Thanks everyone for all your responses. I ended up buying the Think Tank Streetwalker. I think it will work perfect for what I want. I don't have large size lenses..so I don't really need a super huge bag. My original thought was to get a big bag to store everything..but I played around with my Lowepro Flipside 300 and could fit everything inside, though it's tight because Lowepro has thick padding and it has that stupid pouch toward the top. The Streetwalker is a hair bigger but has thinner dividers and no pouch and it's a couple inches longer. I figured I will have enough room for an additional small lens and flash. After this last two items, I don't see myself adding anything else for a while. I built up a kit that I really enjoy using and want to start focusing on taking pictures rather than gear.
Anyways it has a lot more compartments than my Flipside 300..but the reason why I got the Lowepro was the size, I could easily bring it on short hiking trips. So I thought if I was going to spend money on a new bag, I'd use it as intended instead of sitting on my floor for storage. I have drawers for stuff I don't use often and they can stay in there until needed.
Watched many, many reviews on this bag and just fell in love with it, it looks better..love Think Tank reputation and I guess their warranty policy is quite good. I thought about getting the PRO version, but the way I looked at it was pro lenses like the 14-24, 24-70, 70-200 or 300 2.8 lenses..big huge filter thread lenses and for pro bodies with the grips. I don't have any of that, their for it didn't make sense to get it.
I'm sure I'll continue get more stuff..but you just can't fit EVERYTHING in one bag and I just don't have the funds to buy a huge ThinkTank airport bag, lowepro roller or a pelican case..plus half of it would be empty!
Anyways, Think Tank has a good return policy..so if for some reason it doesn't work out in 30 days, I can return it for a full refund and no restocking fee and get something else. Its worth a shot!
If I do grow out of it in the next few years, I could sell it and get most of my money back as they do hold their value.
Never thought I'd be a owner of a Think Tank bag...
