I couldn't agree more. however getting ones hands on one of these is somewhat difficult and at a voltage that is readily usable can also be problematic without step up or step down transformers which in the case of step up are very expensive.

I wasn't necessarily referring to use in the US, however importing one from Japan is still problematic unless you travel there or have someone act as proxy and ship it to you. As the referenced article stated, getting a Japanese retailer to ship one out of country is very difficult. I've made many purchases of JDM products from hi-fi gear to televisions, none have been accomplished without either an extraordinary merchant or a trip to Japan. I was very fortunate for many years to travel to Japan many times for business and was therefore able to purchase goods and import them directly.
