Us broadcast engineers bought a bunch of DTV converters that were
available around here and tested them in bad locations. The Zenith
DTT900 was the best of the lot as was the Insignia that Best Buy sells.
This is not surprising, because they have the same circuit board, in
fact, the FCC number on the bottom of the two units is the same.
The RCA and Magnavox units sold at Wal-Mart were inferior in every
respect. The only redeeming value of the Magnavox unit is that it has
analog pass through.

Another good unit is the Channel Master DT7000. It has the added
advantage of S-video output, it has a really great picture on a set with
S-video input. The fringe area performance seems comparable to the
Zenith DTT900.
