If your DirecTV HR21 leaves you feeling empty because you want need to streamline your over-the-air ATSC side of the house, listen up. DirecTV's AM21 is your answer. For $59, you can pick one up, stack it above or below your HR21, connect it via USB, and bask in the glow of dual tuner ATSC programming (integrated with your OSG, to boot). It's not a bad looking little black box at all, and the price is reasonable. It's being shown off at CES, and you can expect it to be available at the end of February.
