Bill,
I called monday. Maryann was off, but the lady I talked with took my phone number and said that she thought they were not going to sell the last 3 as they may be needed for replacements. She promised to call after talking with Maryann. 
So, I'm hoping that IF the last three are to be sold...there is really only 2 left!                                                                      Lary Coltrin
