After the no luck trip to Westminster, CO Circuit City on Tuesday, I first called the Lakewood, CO store on Wednesday morning. Gal answered that they had a lot of Zenith boxes, so I asked her to check to see if any were April manufacture date. She checked and said a bunch of them were.
I went to that Circuit City late Wednesday PM. They must have had 20 boxes of Zenith DTT900s and only a few weren't April builds. I bought two of them with my coupons.
Hooked up one of the Zenith's to an ancient Radio Shack 13" TV that we keep in our 2nd floor home office. With an old variable amp RCA set top UHF/VHF antenna, I got 6 of the 9 stations that I get with my other HDTV tuners and an amplified attic antenna. The Zenith clearly has an excellent tuner, maybe even better than the one in my LNT3253H Samsung LCD HDTV.
I'm very happy with the unit. I even love the "Gort" color eye. My only complaints are with the remote and included cables. First off, you definitely need to point it exactly at the units and TVs IR sensor and you'd better not be too far away. Second issue isn't the remotes fault, but the remote's IR signal for the up-click button matches an OFF signal for the old Radio Shack TV, so whenever I use it, if I'm not careful, I end up turning off the TV. Finally, that included coax cable is a joke. I doubt that it is even RG59 in wire gauge standards and practically has no insulation to speak off. I used it for a little bit before hooking up the composite cables and got a lot of signal breakup that went away when I stopped using it. I strongly recommend to anyone planning on using the RF input to use a good quality RG6 coax cable or at least a good quality RG59. It will really make a difference compared to the coax cable provided by Zenith.
