I have a bag that I want to sell. It's pretty big. It's a KATA HB-207. Like this

I can fit 2 bodies, a 17" laptop, a 70-200, 16-35, 24-70, flash, 100mm macro, and more. you can even strap a tripod AND monopod on the sides.
I've had it about two years, and it's an amazingly well built bag, I just don't use it. I stick with my pelican case. I even have the optional dolly that you can use with it, which has NEVER been used.
You can see some details here:

I'm willing to sell it for $150 plus shipping and paypal and I will throw in the wheels.
Lemme know if you want to see some pics.
