I stumbled across these canvas bins on amazon and saw a bunch of reviews that they worked well in expedit cubes. They arrived today and they are great! Fit perfectly on the side with just enough room at the top to see what is in them. I bought them from a 3rd party seller for $6.99 each but they seem to be out of stock (Today's Housewares).
