I was looking for a good storage solution for my Sizzix dies and chose the ClosetMaid 8 cube organizer in espresso from Target along with 8 canvas storage cubes in black and chocolate. The system cost a little over $100 for die storage. But I just LOVE it. Each canvas cube can hold over 20 dies. I have them organized by:
Tim Holtz Collection
Envelopes & Tags
Frames & Flourishes
Shapes
Seasonal
The cubes will accommodate strip dies, but the XL dies do not fit. So I store those in a basket next to my cubes.
It is very easy to pull out a canvas cute and find just the die I'm looking for.
