I have installed dozens, if not 100's, of 722ks (and 100's, if not 1000's, of 622s / 722s /612s) and not a single one has come with anything more than: Composite cable (yellow/white/red cable) & phone cord, just like 622, 722 & 612 (the 622 & 722 did come with an svideo cable which was never used). We get our equipment straight from Dish and do not open the boxes prior to the customers house. The bulk Component and HDMI cables that Dish sells us come in a plastic bag, they are the same cables DNSC uses. If you are getting the cables with a 722k brought out by a tech, they are probably bringing in those cables at the same time. If you are getting the cables with a 722k that has been shipped to you, they might be throwing in the cables to lessen the possibility of needing a service call to hook it up.
