I have spent many hours researching the various switches for DirecTV. I would appreciate any recommendations or feedback before I purchase. I have standard dual-LNB DirecTV dish. I'm adding receivers so I need a total of 6 outputs. I've looked at the following switches (3x8): Channel Master 6228IFD Perfect Vision PVMS-8EP Eagle Aspen S-2180A-LX Is anyone familiar with the quality of these switches or manufacturers? Can you recommend one of these or perhaps some other brand? Thanks.
