GE - Digital to Analog Converter Box Review

This GE "Smart Digital Converter Box" 22729 from Target gets my top vote compared to the Venturer STB7766G (also from Target) and the Insignia NS-DXA1 (from BestBuy). I swaped these three units in and out of the same setup. I'm at a considerable distance, with hills in between, from the PBS station I wanted to receive. That station puts out three signals (channels 30-1, 30-2 and 30-3). The Venturer only got 30-1. The Insignia 30-1 and 30-2. The GE got all three channels. Also, the Insignia required that I increase the TV volume way beyond normal to get the same volume I normally listen at. There is one down side to the GE unit -- when stations are added via use of the auto scan feature it is not possible to remove any of them from the setup after the auto scan is done. In my situation the GE found two radio stations and added them to my setup (channels 30-4 and 30-5). It is possible to manually add stations to the setup, but only the primary station (in this instance 30-1). Sub-channels, e.g. 30-2 etc can not be added manually. (I am not using a GE "Smart Antenna" with this converter box.)
