Can you help me find the perfect reusable shopping bag?

Things I’m looking for in a shopping bag:

* Big and strong enough for groceries
* Stands up on its own
* Easy to fold/store
* Long, over-the-shoulder straps
* Easy to clean
* Relatively attractive

It also needs to be affordable, as I’d like to buy several of them. This bag seems to meet all of my requirements but I’d rather not be a walking advertisement for The Container Store (or any other store, for that matter). A small name or logo would be ok, but it shouldn’t be the main focus of the bag.

Does the bag of my dreams exist? Can you point me to it?
