What are good school/book bags for high schoolers?

I will be a high school senior next year and my course load (textbook wise) will be somewhat light. I'm looking for a book bag (not a backpack) to use for next year that will be big enough to fit a binder, school supplies, cell phone, notebook, iPod, wallet, and a mini laptop. School doesn't start for awhile but I want to figure out how much I will need to save up to buy a book bag before school starts. Thank you!
