When I bought my gear in Dec I made a common rookie mistake of buying a bag that is way too small. It was fine for my D3100, the kit lens and the 55-200 that I got originally but now I bought two new lenses on ebay and at some point need to get a proper flash unit so I'm out of room and need something bigger. I was on lowepro's site (since I like there bag) and when I punched in my requirements it came up with the Prorunner 350 AW. It's a pricey bag at $200+ from lowepro directly and about $170 on-line. So, I'm looking at whether there are good alternatives that will meet my needs (a quality bag that will carry my camera+lens and 3 other lenses and a flash unit when the time comes as well as my tablet.) Thoughts??? Thanks!
