To my forum friends: I wanted to help my sister out by getting her a new dish so that she can see HD programming. Right now she has one of the 3-pronged LNB dishes but I would guestimate that it's about 5 years old. She has one H21-100 HD capable receiver but doesn't see any HD programming at this time. We're talking 18353 zip code. She was recently able to see the HD channels that resided in the 70s until they were taken away on April 1. I know most of you are gonna say, "tell her to call DirecTV and they will give her a new dish." If that's what I wanted to do, I woudn't be posting in here. I wanted to keep it a surprise and I was gonna help her husband set it up on our own. Besides, doing it ourselves feels better, doesn't it? So I was wondering which is the correct dish to get? I've seen so many different types out there that I just don't know which is the right one. Is this the one to get? http://www.solidsignal.com/pview.as...-SL3-LNB-Combo-(AU9SL3)&c=DIRECTV Dishes&sku= Or is it this one? http://www.solidsignal.com/pview.as...C-HD-Programming-(AU9S)&c=DIRECTV Dishes&sku= Or this one? http://www.solidsignal.com/pview.as...d-SL5-LNB-Combo-(AU9SB)&c=DIRECTV Dishes&sku= or this one? http://www.solidsignal.com/pview.as...SL3-LNB-Combo-(AU9SL3B)&c=DIRECTV Dishes&sku= Is there a difference? Must be some if the prices are different. I was looking to see if I could find one (even used as long as it's not dysfunctional) from $30-$60 or so. Would anyone recommend a bargain site other than rolling the dice on eBay? Any help out there? Again, thanks for everything Guys!
