I have the Delphi SkyFi II, and I love it. The Roady2 is also a good receiver. The nice thing about the Skyfi II is 1) it will alert you when your favorite artists have songs playing and 2)it has a pause feature that can basically pause the station for up to 30 minutes, similar to a Tivo. Then you can fast-forward back to realtime.

The MyFi's (basically an XM Radio walkman) have also come down in price a ton.

Just found the SkyFi II car bundle for $50... Not sure the 30 minute pause is worth the extra $30 since Bob Dole will be listening to tunes about 99% of the time.

ARGH! The choices!

I'd imagine programming is quite similar, save the NFL. I don't care about that. My problem with Sirius, is their tuners are just too damn pricey compared to XM...
