I missed the $50 rebate but decided to pick up this unit anyway from my local Fry's in Renton (Seattle, WA). Grabbed the last one on the shelf for $99.99 + tax.
So far, I've tested at home in Mill Creek, WA and at work in downtown Seattle, and the reception of HD Radio signals with the included dipole FM antenna has been MUCH better than expected. I'm planning to hook up an external unpowered omni-directional antenna at my home in Mill Creek to pull some of the harder stations (i.e. KNHC-HD, 89.5 & the digital signal for KWJZ-HD, 98.9).
Even though KING-FM has three HD channels (HD1, HD2, HD3), I've been extremely happy with the SQ performance of HD1. ... So good, I can roughly approximate when a recording of a piece was made (60's, 70's, 80's, etc.) from the SNR of the microphones used (hiss) where the SNR of the channel is much higher than the actual recording.
