For what it's worth, NPR sells non-HD (Wifi) radios on its website for an average of twice what they're worth. $200+ vs. $75 I paid for mine just buying it from a retailer the normal way. Expecting users to fork out additional cash for the even more of a niche-item HD radio should be a no-brainer for them. They'll take a $200+ HD radio and find a way to net $350 on it in no time.
Besides, if you don't happen to like classical music as much as the next guy, there were many moments in the day where you wouldn't stop on or listen to WMFE for extended periods of time--since you weren't engaged into any of the music being played. At least now, the information/discussion might interest those who'd normally pass by the frequency.
Of course, this is just my opinion here.
