They offer full warrenty if you want really cheap you can look at ebay. Its a fair amount cheaper and ebay has a warrenty program on electornics if you want.

I really would suggest a 4 channel amp before you get components. Itll help the overall sound out a lot and most components really need amp power. If you want components ive herd rainbows that sound really good, the alpines i have are cheap on ebay (200) as opposed to 380 but they need a fair amount of power (atleast 75). The alpine type r's aren't bad but its all taste. Everyone has a different opinion on what speakers should sound like.I personally tend to like soft dome tweeters cause they don't seem to be as harsh as metal. Thats just imo though. Best bet is to go into some shops ask questions and audition cds you like. Don't be afraid to ask them to play something you are familar with.
