UPDATE (04AUG2009): Never say never, I guess. SFX Performance sent me my order -- insured, this time -- at their cost. It actually arrived a couple (few?) weeks ago. Much appreciated. As far as I'm concerned this event has come to an unexpected but positive conclusion.
UPDATE (07APR2010): Updated post title.
