Alritey.. Well I've been sitting on some xmas money, gonna save part of it for my move. But I want satellite radio for my car. I love music so I think it'd be something I'd really enjoy. Got a gift card to best buy, so I figured why not put it towards a radio.

I just want some input from you; if you have one or you know anything about it chime in.

Seen this and thought hm that's nice, but seems too cheap. Oddly cheap. XM Onyx Satellite Radio Receiver with Vehicle Kit XDNX1V1 - Best Buy

So then I seen this. SiriusXM Edge Dock & Play Radio + PowerConnect Vehicle Kit SX1EV1 - Best Buy
And this Sirius Starmate 8 Dock & Play Radio + PowerConnect Vehicle Kit SST8V1 - Best Buy

Like sirius, xm, siriusxm; just what in the hells the difference and what all do I need?
