Samsung SIR-T351 ATSC (HD) Tuner
Cheapest for a Reason
I've had good experience with Samsung in the past, but don't go for this unit unless you already have a near-perfect analog signal.  I'm 2 miles from the broadcast stations in Chicago, but in an apartment.  I would get 8 out of 10 bars in signal strength, but the unit would have to keep honing in on the signal so the signal strength bars would 'flicker' and as a result audio and pixilated picture would constantly come in and out despite all amplification attempts.  I now get shadows with my analog set up, so my guess is that the reflecting in my indoor signal is causing both the analog shadowing as well as the transient at best HD picture and sound through this unit.  I believe it's an issue with the processor not being able to re-adjust quickly enough and filter down the signal it needs just right.  I also must reiterate the issue that you can not view the menu in 1080i through the DVI and this unit does NOT come with a DVI cable so expect to shell out another $100 for one.  If you have a roof antenna, then then this may be the unit for you, but I'll try out the 4th generation Samsung TS360 and hopefully it will be able to lock onto my bouncing but strong signal - plus it comes with a DVI cable.  I still applaud Samsung for leading the way in driving down the price of these suckers &amp; releasing the better technology with better consumer end-user specs before everybody else.
