The only contact they have on their site is the phone number from their Tokyo shop, I even tried to send emails to info & office at but they don't have a mail server setup.

I'll try to call tomorrow, hopefully get some info. I'll also ask them for shipped quotes for US West & East coasts and I'll post those.
Sunbeam Corp. is the main site and Sunbeam Ex is a sub site.
They have email address on Sunbeam Corp. website,
