Are there good sources for pre-owned or new-old-stock DTT900 or DTT901 CECBs? I gave away both of mine to parents who relied upon OTA. I do recall it seemed to be a very good box, the only gripe was the remote control buttons were very small - and of course the original DTT900 units did have an audio problem with distorted sibilant sounds.
Per Amazon's reviews:
DTT 901 - current price $124.99 - 192 REVIEWS, 4.4 out of 5 stars
DTT 901 (different listing) current price $116.98 - 15 REVIEWS, 3.93 out of 5 STARS
DTT 900 - current price $94.99 - 4 REVIEWS, 3.75 out of 5 stars
Insignia DX-DXA1 - current price $110.00 - 70 REVIEWS, exact star rating not shown, 56 out of 70 reviews are 4 or 5 star
The big drawback to these products is that the manufacturer warranty probably would not be honored with a "new old stock" unit, and certainly not with a used unit.
Here's what I found on other CECBs which appear to still be in production:

There are more, but I think we are getting the idea, the best overall CECBs are no longer in production, and in general reading all of the different reviews, it is apparent that even the LG/Zenith/Insignia CECBs do have a somewhat limited life expectancy.
CECBs by Sunkey and Apex are rated very low.
