Im looking for a site where you can buy Japanese ESP's.
I really want an MX.

MX's on Ebay go for $2500 on ebay. You can talk to your dealer to see if they can order one for you, or go to Japan yourself, and place an order. Then go back in a few months, pick it up, and ship it to the US. Unless of course, you know someone who lives in Japan that can do this for you.
Ikebe Gakki and a few other people do export guitars to outside Japan.
