Hey Juicy, DEFINATELY get the Sportster Replay, it's the best. It got one installed in my vehicle a couple of weeks ago and I love it. The nice thing about it compared to the cheaper models is that you can pull the receiver out and pop it into a boom box or into a home docking station which is neat. It also has a 44 minute save feature for when you wanna hear a kick ass song over again

It says $169 there, I bought mine at a local radio shack for $149 (I'm sure other local stores sell it for the same cheaper price), plus it has a $50 mail in rebate, so it's only $99.
