Just out of curiosity - how did you determine the Playmaker was not working? What troubleshooting steps did you follow? I'm asking because I had mine (PL-7000) for 5 years and it works great.
You do realize that the PL-7000 is the original Playmaker. It supports only one receiver and gets signals from only the western arch satellites (110, 119, and 129). Which is great for areas west of the Mississippi and not so good for eastern USA.
The PL-8000 is the newest and most improved Playmaker. It supports two receivers and gets signals from both western arch and the eastern arch satellite (61.5). This makes it the most capable antenna in the Playmaker line.
