Can anyone recommend me shoulder bag (preferably a messenger bag) that could fit:
-Canon T1i w/ battery grip
- 18-55mm attached to the T1i
- 55-250mm f/4-5.6 lens
- 50mm f/1.8 lens
- Canon Speedlight 430exII
- some space for batteries and chargers.
- Additional space for notebooks (if possible).

My old bag is starting to rip badly, so I need a replacement.
I'm looking for a bag that's under $80, but the max I'll go is $100.
