Harley Benton would be a good start. [br]www.harleybenton.com
however you really should try to get into a store where you can try a few models out. Even if you can't play a single note it's important to find one that feels comfortable for your size. At 6-3" I'm guessing you have large hands and most electrics have narrower necks so fretting strings is a bit more of a challenge with large fingers.
just a thought. Good luck and have fun with the whole process. [br][br]
