I've had my 48" WS Mitsubishi TV for about a month now, and I'm getting the HDTV itch. Problem is at $500 - $800, I'm having trouble justifying the expense. I do live in an area (Columbus) with seemingly good over-the-air HDTV signals. I also have a DirecTV/TIVO unit, so my ideal would be to get the HD version which should be released late this year. I'm not sure I can wait that long though, and I'm sure those units will be pretty darn expensive upon release. What are the chances the prices of the current HD/DirecTV receivers will drop to the $250 - $300 range relatively soon? Then I can TIVO regular broadcasts while enjoying HDTV broadcasts, which may also curb my "need" for the HD-TIVO unit later. If the prices of new units aren't expected to drop any time soon, what's the best way to get a good refurbished unit?
