Wheeled Laptop Backpack

I want to find a backpack on wheels beautiful bag for laptop / which is between $ 30 - $ 60, and is best leather. I know that leather is more expensive, but it does not have to be branded or fancy or anything. Preferably leather brown or orange. Any ideas of where to find something like that?

Idea here:
Go to http://www.ebay.com . Search just click with keywork "laptop bag, laptop case". You will get results very well with all types you like.

I alway buy item on eBay and I love to see the laptop bag.
