Of the few that are available in local stores, I purchased these to try out:
-Radio Shack Digital Stream DTX9900, $59.99 before coupon.
-Best Buy's branded Insignia NS-DXA1 (same as Zenith DTT900 sold by Circuit City), $59.99 before coupon.
-Channel Master CM-7000 from Fry's, $79.99 before coupon!!
I didn't even bother with the known cheap $49.99 and known no good RCA and Magnavox boxes sold at WalMart. Won't shop there anyway for personal reasons.
In my opinion, so far, the Radio Shack Digital Stream is the best.
I like the larger remote, more ergonomic, controls TV power, video source and volume also. The EPG is more extensive too, shows current and several hours ahead.
The Insignia/Zenith remote is too small & uses only one AAA battery.
The Channel Master from Fry's was promising looking, nice metal case, S-Video output, but too expensive ($79.99 before coupon) and won't control TV power & volume. Very disappointing, expected better from Channel Master.
All seem to have equal picture quality to me using a CM 4228 8 bay UHF antenna with rotor.
I wish that the Digital Stream D2A1D10 was sold somewhere as it has an S-video output, but it seems non-existent so far.
I would be interested if anyone has tried the Digital Stream DSP-7500T or DSP-7700T?
