Need ATSC - QAM - HD TV Tuner for 720P HT FP

I'M not finding much more than sketchy info on quality ATSC tuner/receivers used primarily for OTA HD TV and/or CATV applications, in the current 2011 market.

The only ATSC tuners I've ran across which seem to be noteable and available are from Channel Master 7000/7001, Cintronics ZAT , P/N DCT102 , and a couple of names I've never even heard of! Some of which are listed but said to be no longer available. Kworld for example is listed but unavailable at Amazon.

My intention is for use with an older analog TV set, and of course the BenQ projector.

I'd go out via RF or RCA/S Vid, for the analog TV and HDMI for the BenQ FP, and TOS to a processor.

I’d probably also go off for a rotor antenna… eventually. But use my std outdoor ant for now.

if possible.... being able to connect this tuner/receiver to a LCD pc monitor would be great too as I've a couple of these VGA and DVI laying around doing nothing.

Anyone who can shed some light on this situation for me as to which are quality products, current issue, etc., I'd be quite grateful.
