iBiquity has another HD Radio rebate offer that's running from April 29, 2007 to July 3, 2007...celebrating the graduation season. $40 off most HD Radio receivers...not too shabby.
Here's the press release:

I've also heard that from April 30th to May 12th, Radio Shack's Accurian tabletop HD Radio (catalog # 12-1686) is on sale for $169.99. The RS website also links to the aforementioned iBiquity rebate, so the final price would be $129.99. I believe it's same price online or in the store.
As reviewed in Radio World not long ago, the Accurian has no alarm clock, but is overall a pretty good tabletop HD Radio.
