it boils down to: if you do alot of driving then yeah it's worth it. if you're only going back n forth to work 20-30mins each i'd say no. you have FM, CD's or your IPOD to listen to in that short run. i have sirus but i only got it cause i'm a truck driver. going through city after city too many stations come and go you spend so much time just changing the channel. it does have a bunch of things to choose from. things from the elvis channel to 50's 60's 70's 80's 90's to heavy metal, rap, to buisness, cnn, to any sports game, to old shows that use to only be aired on the radio. there is something for everyone. as for cost, it depends on what package you get. they offer like 6 packages that range from, 7-20/month or save more money by payin yearly either 1 or 2 years
