My first board was a Morrow Lithium, and it was more than good enough to get me started in the sport. Be more concerned that you're getting the right type of board for what you want to do, i.e. don't get a noodle for downhill or a plank for park. If you only spend a small amount of money for your first one, then you won't feel bad about tossing it aside once you have more experience and have formed an opinion on what boards you'd like to have.
I'm sorry. Was I talking while you were interrupting?
