an alternative to this stew mac product?

[Jim Figurski]

I have no problem with purchasing this product from Stew Mac, but I don't want to pay the outrageous shipping associated with it:

I'm thinking there has to be something out there like this, something I probably already have in my home that I could use that is like dense or heavy foam for sanding.  Any alternative ideas come to mind?

Hope I am not too late to offer a suggestion.  Try a Preppin Weapon available from Lee Valley.   I have one for 120, 220 and 400 grit.  It is an excellent sanding block.
