Casio wk 1200 details needed

[yogesh2708]

Hello friends..
  I am going to buy a used keyboard casio wk 1200 at very cheap price of 6000 INR. I'm a beginner and haven't used a big size piano yet, so I don't know many of the features of such a keyboard and what are they used for.
 Actually I'll have to travel a long distance to reach to buyers home to buy the keyboard. As this is very cheap I doubt that there may be some effect in the piece so I thought to directly buy from buyer after checking its condition instead of buying it by courier.
  So please tell me WHAT FUNCTIONS OF THIS KEYBOARD SHOULD I NEED TO CHECK TO ASSURE ITS REAL CONDITION?
   Please tell me what are the accessories I should ask for to the seller eg. Midi hub, usb cable etc
  Thanks...
