We should do this.  Set up a test station for the common ones. Ua726, 
SSM2040, SSM2044,  etc.  IF EBAY would just COOPERATE TO REMOVE THE SCAM 
IT IS SO FLIPPING EASY.  When someone sees them, order a couple.  IF 
they are legit, great.  If they don't meet specification, report to ebay 
and have them removed and all their funds returned to buyers.

Once these idiots figure out that it's a losing proposition they stop 
doing it.

Everyone forward this suggestion to ebay.  Let's just pester them into 
agreeing to do it. -Bob
