The vast majority of people on this site will give the answer to this question in a very well worn, constantly repeated cliche, but, that is because it is the best piece of advice you could ever have for buying a new guitar!!
Forget all about brands and what you see your favourite guitar heros playing (they are usually endorsed and playing those axes for money) and just try out as many possible guitars as you can until you find one that feels like an extension of your body and really sings to you, you'll know it when you find it!!
I think I read someone hear say on a similar topic "Close your eyes and open your ears" (Lordathestrings maybe??). Nuff said.
Good luck.
