Multiple Camera and lens bag

I am looking at purchasing a new bag. I will be using it for the following:

1. 2 Canon 40D's
2. 2 Lenses (no long range zooms)
3. Batteries and accessories

Looking to spend around $50 or so dollars. Does anyone make one that would fit my needs and budget?

Thanks

Buy the insert of your choice first - I use Domke.
Then go to your local discount luggage store or online and buy
a discontinued $180 bag for $19.99.
I did this at Tuesday morning and the bag is an 18 inch Pathfinder.
Your size brand or dollars may vary.
