Where can I find a decent looking laptop bag for a 17.5 inch Toshiba?

I'm having a horrible time finding a suitable laptop bag for my 17.5 incher. All of the nice looking ones are for much smaller models. I've come across some that say they will "fit" up to a 17.5 inch, but I also worry about the strength of the bag and straps. It's a Toshiba Satellite. Does anyone have any personal experience with bags to fit this or a similar model? The only ones I've found that might work are very basic, cheap-looking black bags. I'd like to find something a bit more fashionable before settling on something for function alone.
