DISH TV is currently offering KAON Receivers but the software is controlled by them which means lots of options available on normal receivers are not available even something like deleting channels. They are promising in future they will implement software that will allow further options but as of now not much to offer other than what you have or a KAON Receiver. Even in KAON the software is controlled. And the receiver and card are matched so you cannot use any other CONAX embedded or CONAX Cam to watch DISH TV !
Enjoy with what you have at the moment and wait till they have more to offer !
