Anyway, Like Hunter said... It depends on your experience level. I'm a firm believer in the philosophy that a beginner should start out on a beginner guitar. It just makes sense. 1. because not everyone takes to the guitar like others do. Some people get bored with it and end up not playing much at all... if at all. So you end up with a wasted investment. Guitars really are investments as well... and it'd be pointless to spend 350 on something that you're not going to get your moneys worth... 2. Like Hunter said, you're going to want to upgrade in no time at all. You're only 15 years old (Happy Birthday mate)... so you're going to have PLENTY of oppertunities to get some nice gear in the future... Be patient and go for the less expensive model. You can always keep it around and upgrade the pickups and hot rod it in the future when you get a real job and get more into the guitar.
In the end though, it's your money and it's your decision. My recommendations are just based on my experiences as a beginner guitar player when I was aroudn your age... I hated my cheap Strat that my parents got me... but I love it now and I wouldn't have it any other way!!
