I'm looking to replace my microHD. Sadly it died a few weeks back. I have the 3500HD and to be cruelly honest I do not care that much for it. The one thing I do like is being able to pick up XM radio on Galaxy 14. I have the Manhattan 1933 and I'm hoping that 1997 can pickup the radio stations as good as the 3500. I would like to know, other than IPTV, what other features makes this unit better than the RS-1933 and 3500HD.
