I found this building material at solarbotics and was wondering if any body has ever used it and how strong it is

It's what I'm going to be using for my robot! This robot is made out of expanded pvc (sintra) http://letsmakerobots.com/node/2938

The 6mm expanded PVC is quite rigid.  Here's a shot of a high-wire challenge robot we made.  The bottom bot uses it.  It's easy to cut, machine, drill & tap.  I've also used aluminum threaded inserts with great success.
