How can I boost my FM receiver without spending a ton?

So I guess that just leaves the question - which is better, XM or Sirius ?

i just talked to an audio installer about this the other day. he told me it depends on your type of music you like so check the listings but sirius has something xm doesn't right now according to him and thats u can use it like your dvr sat box for tv. u can pause the live feed and u can rewind up to 44 min on some units that u buy. so say u turn it on and just missed your fav song u can rewind it to the beginning of the song. something to think about
