What is a good , large bag for my digital camera?

It needs to hold my SLR camera, 2 lenses, extra batteries and a external flash. Unfortunatly I don't have much$ so I need it cheapish!

Best buy used to sell the Canon gadget bag... for about $20.... this was the same bag that canon included in their $120 kit which came with an additional battery and filters. I purchased just the bag and I love it. I holds my Nikon d50 an extra lens, my camcorder, and my smaller Sony-v1, and all of the associated accessories. I would recommend this bag.... Not sure if the price is still the same.....

A regular backpack with lot of foam to support the gear.

Some great bags on eBay

Tamrac makes some really nice camera bags. I have one like this one:

It has plenty of room for a camera body, two or three lenses, a flash, and any other small miscellaneous camera parts. Plus it's only $35.
