I bought the Sportster around the end of November, and love it. Yeah, I bought it for Howard, but I'm loving everything else about it, too. I'm also a big NPR listener, so I'm very happy that there are three channels devoted to NPR. And the music is fantastic. Like Elvis? There's an Elvis channel that plays Elvis 24-7. My favorite is Left of Center (channel 26). Lots of indie and college rock.
But the best feature isn't really advertised that much. I love how you can have it broadcast on whatever radio frequency you want. Does the S50 do that, too? This means that I can have my Sportster on in the boombox in my kitchen, and tune in to the channel it's broadcasting on any other radio in the house. So I can listen to it while I'm getting ready for work upstairs in the bathroom on my little radio, or even in the basement on my stereo while I'm on the computer. The range is great, too. I can pick it up the frequency even a few houses away!
