Myn is a made in Japan Tokai, LTD Edition only a small batch came to the UK, i havn't tried the Korean one but my Explorer is easily the best guitar i have ever played. Tokai are great, i haven't heard a bad word about the Jap or Korean ones, great all round guitars and are getting to be strong competators to Gibson.
Unless you are getting the MIJ one i have then i would try it first. But as i said it doesn't matter where it is made, Tokai are great guitars.
