I know I am going to be told to go back and read but there are so many posts and replies about this I want to get a pansat I would like to know which is better 2700 or 3500 how long do the channels stay for and is it easy to program the keys and such I can pretty much follow directions I mean the directv thing was simple you get the bin and insert the card and bam is this similar to that I mean I am not an idiot or anything I just really want to find out how difficult this will be before getting one and also is there any other equipment needed for this besides the fta and my directv dish thanks in advance
