Hi Kunny,
You want an A-90 and me the board VE-RD1 inside of it.
There's a person on this board selling an A-90EX with the board for $1500.He'll pay the shipping.
What about we get it together? You pay $1300 for the keyboard and me $200 for the board and we can ask him to ship each part separately.
Regards,
Fernando
