I just ponied up last year. So here are my thoughts.
I am assuming you have a slimline 3 HD dish that has built in SWM capability.
So find out if your new receiver is SWM compatible, I assume it is since I have one relatively new one that is.
I take the Genie receiver with me when i travel. i cannot stand to watch live TV with commercials. So I watch mostly recorded stuff so i can fast forward thru the commercials.
My Slimline 3 hooked to the Genie still gives the same old signal tones when aligning the dish.
When doing the final tuning, The wife and I put the cell phones on speaker and I can hear the tone outside at the dish and she also gives me the % signal.
my story and I am sticking to it. You just cannot beat that capability of recording multiple programs over one cable.
