Had the original, loved it. When it died horribly, I purchased this second generation HDHomerun and I love it, too.
It does not have an IR receiver, for those who care, and it has a single coax cable input rather than the separate inputs of the first gen (useful for, say, having one OTA and one QAM).
For those with antenna concerns, I made an antenna similar to this and was able to pick up every UHF/VHF station we had in town. I used copper ground wire scrap from electrical work I was doing in the house and scavenged wood, nuts/bolts so the whole thing cost me zero dollars + time.
Oh, and the added bonus of the look on my wife's face when I used an old vice to hold the thing vertical.
Honestly, though, that was a couple of years ago. Perhaps those sweet flat panel, 30 dollar UHF/VHF antennae have excellent reception now.
Regarding UHF/VHF: Most OTA digital channels are broadcasting in UHF but, once the analog channels were shut down, some switched back to their VHF frequencies. PBS is the notable one, here. Something to keep in mind.
