I purchased the Sony XDR-F1HD used off of Amazon marketplace for $67 delivered. My first expression is wow!
This radio sounds absolutely great
with analog FM. HD radio streams will vary based upon bandwidth and how much compression the radio station is applying to the transmission chain. Still, when the Sony gets a good signal lock the better HD stations sound superior to the already excellent analog FM playback.
As others have noted, things are more pedestrian on AM reception. My reception is pretty challenging as I'm an a first floor condo with the standard Southern California chicken wire and sprayed stucco construction.

I'm going to take stevec50's advice and try a 102" CB antenna from Radio Shack out on the porch to see if I can get better reception. I've heard pretty good things about using an 8' dipole for FM reception; I was surprised to hear that this might work well for AM reception as well.
Overall this Sony HD tuner is an excellent tuner. I'd recommend trying one out if you can find it in stock. Even if you decide you don't like it, you should be able to eBay it for about what you paid for it.
I'm really happy to find a product that works this well for such a low price. Listening to the radio is fun again!
