Quite a few forums out there that cater specifically to EDC (every day carry) related items and of course the bags to hold it all.
Milspecmonkey is a great resource when it comes to reviewing bags of all different sizes and types.
Maxpedition makes great stuff and is made in the USA as well. 5.11 is another popular choice.
Ill freely admit to carrying a "murse"
and one suggestion I can make is to avoid the "sling" style bags with only one strap. Especially for a BOB which will weigh quite a bit, sling bags will start becoming uncomfortable quickly.
If your leaning toward a "72hr." Type backpack, 5.11's tier system is nice in that you can easily attach some of their smaller bags onto it with the included straps.
Hope you find what your looking for! Also try ebay, I've sold a few bags that just weren't quite what I was hoping for and you can sometimes find some deals.
