I'd suggest the Lowepro Flipside 400AW.

It's a bit more than you want to spend $149 in both the US and Canada but I think it would be worth the extra money.


It holds like 4 extra lenses and has a front pocket for you personal stuff. A standard tripod holder in the centre of the bag, but on the side are two mesh pockets with clip-straps. So you could theoretically stuff your lighting stands into the mesh pockets and secure them with the clip-straps. That way you can carry everything in one bag (hopefully).


Hope this helps,
