Regarding the Zojirushi recommendation, yes their top of the line rice cookers are pressurized and cook rice much faster than conventional rice cookers. However they are NOT general purpose pressure cookers. It's mainly for rice, you can mix some stuff in with the rice, make porridges and oatmeals, but that's it. Don't expect to use it to say cook a chicken. You can't set timers on those things, instead there's only a list of presets (white rice, brown rice, mixed rice, porridge, etc), then the computer figures out how long to cook the thing based on the amount of content in the pot, automatically. So if you put a chicken in there, it'll get all confused.
As far as power convertors goes, you don't need one. Almost any Zojirushi you'll find in US are designed and manufactured for US. Unless you stumble upon a specialty Japanese import goods store, you won't buy the Japanese model by mistake.
Not all Zojirushi are made in Japan now days. I think their top of the line still are, the entry level ones could be from China or Thailand etc. Just read the labels on the box. Koreans also make nice rice cookers.
I have the exact same one, and have had for around 6 or 7 years now. While I can't attest to it being BIFL it definitely lasts very long, and cooks some of the best rice I've tasted.
