I meet weekly with a group of quilters, and we all have the totes. Mine is the only one with long straps attached to the front and back (instead of just the side hand grips) Everyone says that mine is much easier to get in and out of the car. Here's one in case you aren't sure what I'm talking about.

I'm not sure if the handles will be an issue for you, if you'll just be using it at home...but it's something to think about.
