Dragons4You sells a combo 15qt/32qt rack. It is $205 shipped, so if you got 2 of them you would have 8-10 tubs for $410 shipped. Here's a link....http://www.dragons4you.com/combo_page.html

I can't really tell you much more about them becasue I have never owned one of their racks, but I'm sure someone else will chime in.
