Sony XDR-F1HD

Pros: 1) Easy to use and hook up
2) HD sound quality is much better than standard FM
3) Relatively low priced

Cons: 1) Runs a bit warm
2) Lack of audio out options (RCA only)
3) No tagging or other special features

Summary: The bottom line is that the Sony XDR-F1HD is a great and simple HD radio receiver (hook-up to your amp). It has a small footprint and even though it runs a tad warm, it's not hot like others have claimed; I suppose it mainly depends on where you place the unit. The sound can be near CD quality, but it really depends on your location. Like standard FM, if you're not in the vicinity of the radio station it's going to sound more static (you can go online to check for your location). To tell if you are receiving the HD signal a simple 'HD' symbol will show up.
Finally, the white LCD screen and black casing (with glossy front) makes it very attractive and fits well with my stereo system.
