Thanks for all the replies. CPTBadAss's link led me to the container store, where i found a pretty good solution.

It comes with 12 cases, and one case will hold all but the largest sets. The orange set below is a full wasd set. The only sets i have that wouldn't fit in there were the realforce topre sets. Most of the sets i buy though are TKL, so that works fine for me.
