I find the new TSU-9600 very attractive with its VGA-resolution screen. However, I wonder if there is really that much more to it for someone who does not need the RF extension ability. What else has it got that the TSU-7500 or Marantz RC-9500 don't have? I am about to upgrade my old "green-and-black" RC-5200 and just don't know if the TSU-9600 is really worth it. Is it? What wouldn't I get with the TSU-7500/RC-9500 or the URC MX-3000 for that matter? Thanks.
