I have a few DP301 units currently on my Dish Network 500 satellite dish and I recently discovered that my LNB has gone out for satellite 119. I'm probably going to move up to HD by this winter so I'd like to have an HD capable satellite when I do move up. My question is if I go ahead and buy a 1000.x satellite with the 110, 119, and 129 LNBs will this work for my current DP301 receivers? If so, what satellite do I need to buy? I've noticed 1000.2 and 1000.4 satellites for sale.
