AP420 & AP220 now discontinued - PREVIOUS REVEW - Casio is a famous electronics company from Tokyo, Japan using the latest in robotic and digital manufacturing technology for their digital pianos and other products. I know this because I had the privilege some years ago to visit the Casio piano factory in Osaka, Japan and I very impressed with what I saw. Casio has been making their digital piano line for 30 years which is a very long time in the world of digital piano technology, so they know what they're doing. And as just about everyone knows, Casio is well known for good quality, low priced calculators, cameras, watches, keyboards, and many other electronic devices. I have personally owned Casio products through the years and they have been reliable and useful.
I have written some detailed blog reviews of the new 2013 model Casio PX750 & PX850 (which are available now) so please click on the the links below to find out more about these impressive pianos:)
