I'm looking for a STB HD Tuner with QAM to hook up to a Norcent 32" LCD that I bought. The TV has 2 RF inputs one for analog cable and one for OTA HD feed. But my local TW passes HD QAM clear and wanted to connect a STB HD tunder with QAM and feed it to the TV via HDMI, but don't know if there is a STB HD tuner with QAM out there....I would really apreciate it if somone could point me in the right direction.

You can check the sticky at the top of this thread for a list of available models but the one with the most discussion here is the Samsung. Hhere is link to the thread.
