There are extras you can get for the board, ie, dust cover (important), stand,transportation bag, foot pedal, memory cards,headphones,books,lessons, if you are paying cash i would suggest you try and bargain for some extras ,or discounts,you have nothing to lose.
One of the important things you will find is ,the keyboard is set to flat (sound) (unless its already been adjusted in the shop)once you adjust the EQ, settings the sound of the board will sound even better, also try to have your pc and keyboard close together, if you are learning from the site we told you about it will be easier to relate to what you are learning.mike
