(arg!)Styopa writes "As an early adopter, I have an HDTV-ready set without an integrated tuner. Analog television ends next February. My suspicion is that the $40 set-top box at Walmart has the minimum functionality to get by — i.e. simply a D-to-A converter and not an HDTV receiver. Three years ago I bought a UHF super-antenna (I'm about 40 mi. from the towers: borderline fringe reception) and searched for an HDTV converter to pull down HDTV OTA broadcasts. These were extremely hard to find — none at Radio Shack, Best Buy, Circuit City, or Ultimate Electronics (all the local bigboxen). I ended up buying a SIRT150 from eBay, which never found a signal, despite confirmed reception (on the set's normal tuner) of both VHF and UHF channels. So — any advice on what to look for in a set-top box? Is it going to cost me an arm and a leg, or is it not too far from the $40 Walmart special? Can I use Uncle Sam's $40 coupon towards it? I'd like very much to be able to find a physical store where I could go see the signal, before I decide if HD is worth the up-charge (if any) over simple DTV."
