Sony DHG-HDD250 30-Hour High-Definition Digital Video Recorder (250 GB)
HD Tivo with no monthly fee
I had this unit for about 4 months now.  I had problems a few times with TV guide.  It was very frustrating.  Now I figured out all the problems I had were over the air digital signal problems.  I pay $$$ to get a roof top antenna set up and the whole house wired.  Now it is perfect.  It's like having Tivo and HDTV with no monthly fee to pay.  I got 37 digital channels over the air in the washington DC area.  It's funny that I used to have hundreds of channels on directTV and often found nothing interesting to watch.  Now I always have somthing to catch up on my recorded list.  I can usually finish a program in half of the time by skipping commercials.  Take the time to read the manual and set up the unit, it is great.
