I don't think that this is what the original poster was looking for...but if you want something like that for an over the air antenna that is also inexpensive, then it doesn't seem to get much better than this:

I just purchased one of these since I inherited an old 1080i rear projection tv and it doesn't have a digital tuner and accept high definition over the coaxial input. But, with this box I can output to the tv over hmdi (converted to dvi first). The cool thing is that it has programming information (from tv guide) and dvr capability if you plug in a flash drive or external hard drive. All for around $45!
