Samsung SIR-T351 ATSC (HD) Tuner
Solid performer - strange behavior at times
Have owned this unit since May 2005.  Bought it refurbished for $100.  Works really well except for audio/video sync problems that may be related to distance from the ATSC transmitter.  I have some problems with signal strength when it snows or rains.  I live as much as 40 miles from the broadcast stations but still pick them up fine.  The secret to picking up these broadcasts is HEIGHT!  I have a non-amplified UHF antenna in the attic of my two story colonial that used to be part of my old NTSC VHF UHF antenna.  I live at the midpoint between Detroit and Lansing E to W and between Flint and Ann Arbor N to S and can receive HD channels from these locations without rotating the UHF antenna!
