Jiujitsu Practice Dummies

I'm currently unable to attend BJJ due to a major injury however I would like to continue running through techniques. I was looking into purchasing one of those Jiujitsu dummies that some schools have. I've looked online and seen a few that retail for about $500 U.S. plus Shipping and Handling.

Does anyone know where to obtain some that are made in Canada ( or maybe aren't quite as expensive) or can you only ship them over from the states?
