Do any Japanese (or Japan resident) members have any suggestions on what is the best radar detector to get here in Japan?

I travel on the Shuto and Expressway (especially Tokyo -> Yokohama) a lot and with a 80km/h speed limit, no way I can stick to that!!!

Thanks

 

The Valentine One - http://www.valentine1.com/ ... I used it with no problems and good detection just like the States before I brought it along with me to Sydney. Though, I seriously contemplate where you can get one in Japan. Those published in Japanese aftermarket performance tuning magazines sell some good local ones as well ... Though I don't like the idea of just front detection which is quite useless these days if you're doing some high speeds on that highway.
