The 9uk model comes with a component input board. You will have to buy a HDMI board for your satelite input. Should run around $150.00. Yes HDMI is the best video connection as it is an all digital signal path. The picture quality theoretically be better as the 9uk has some service menu tweeks the 600u doesn't have. However, the service menu should not be accessed unless you really know what you are doing. The reason the 600u is more expensive is that it has some things that the 9uk doesn't. The 9uk doesnt' have built in OTA tuners, a dedicated computer input, or built in speakers.
