SF6 is readily available from specialty gas sellers.  A web search for
sulfur hexafluoride will turn them up.  It's sold by the pound (or kg) and
comes in low pressure bottles (like propane) as a liquid.  The price varies
quite a bit, and you should be aware that SF6 is a pretty potent greenhouse
gas (although there is some legitimate scientific dispute about this, having
to do with actual dissociation rates in the stratosphere).
