Need a decent Japanese keyboard

I currently use an IBM Model M (1391401), which, inherent awesomeness aside, is not a Japanese keyboard.  IBM did make Japanese equivalents of the Model M ( http://park16.wakwak.com/~ex4/kb/tech_bucklingspring.htm ), but stuff like this is going for $250-300 on auctions.yahoo.co.jp.  So, 4channers, do you have any reccomendations as to what a solid, preferably buckling-spring, keyboard would be?  I don't want any multimedia functions or any of that crap, and would be willing to pay up to $100.

Dunno if it's what you want, but, hey, it's cheap.

Yeah of course I've checked eBay.  I'm looking for a good keyboard.  Not some $15 piece of junk.
