March 2003 we bought 2 DP301's at the local Radio Shack and had service installed.
Later we added a 510 DVR with a DP Quad on my Dish 500 then moved to the ViP622 in February 2006.
April 2010 got an offer I could not refuse, straight up trade of my 622 for a 722k, jumped on it.
Right now I run the 722k, 2X ViP211 and one ViP211k off the original Dish 1000 installed in 2003 with my first 622.
