Ok thanks! Yeah asked the seller and he said there was no crown in it, but he's not an electric football player so he might not know what he's talking about. And he said that the board is in very good shape with no dents, but he did say that the vibrations is very weak. So, I told him to turn up the speed knob, but I'm still waiting for him to get back to me about whether this increased vibrations. Other then that though, what could be causing the weak vibrations? I'm guessing it might because the board is old and maybe has been overused, but you guys might have a better opinion!

Thanks again,
Kevin
