Suggestion for an SLR camera backpack with lots of other room?

[dios_et_dios]

I have a Canon XT with a standard and a telephoto lens, as well as a professional flash. I am looking for a backback that is well made that I can securaly hold these as well as a few odds and ends. However, since I often take my camera with me on day/weekend trips, to class, hilking, etc., I would really like a backpack with compartments for the camera and then seperate ones with plenty of space for textbooks, clothes, etc. I have found some for laptops, but I'm not sure they have as much extra room as I would like. Does anybody have any suggestions, or at least a brand with good backpacks. I would love to spend less then $150. Thanks.

Lowepro make some of the best quality backpacks available. They have an excellent range of sturdy backpacks with compartments for your camera, lenses and accesories, including ones for hiking (e.g. Trekker) and water resistant & waterproof ones.

I bought mine at Circuit City. Forget the name decent pack. I store small things in strong zip lock bags.

Sounds perfect, I bought one last year & took it back the next day, it wasn't going to do what I wanted.
I'll be interested to read your answers.
Water resistant compartments sound cool.

Bags these days are so flimsy.
I have been buying second hand good quality older stuff.
Get creative with straps & Velcro, you can tailor your pack to suit the day.
Provision for a strap on tripod is important.
Keeping the camera safe & still having fast access is the trick.
Getting everything on your back is the way to go though.
