6 to 8 hunderd dollars will by a great guitar, after that you start paying for "Name" or "Pretty"
My advice
Go to many shops, play many guitars of all shapes and sizes and do not look at the name of who made the guitar. Use the sound your ears hear to decide what guitar you should buy next. Once you find one that feels good in your Hands and sounds Great to your ears. Buy it. You may find that your happy with a $500.00 guitar.
