This review has been selected by our experts as particularly helpful.
My wife and I had been kicking around the idea of purchasing an inexpensive used piano for some time. My daughter is very involved in school vocal music and we were looking for something that she could use to practice her scales and exercises and improve her musical abilities. We finally decided on this instrument based on versatility, great reviews and the zZounds Pay-as-you-Play option. This is not a plug for zZounds, just a fact.

The piano(s) sounds great!! Lots of variations and subtle nuances in each voice. My favorite is the Bright Piano although the default Grand Piano is amazing. The other sounds are pretty good ranging from orchestral to world instrument sounds and General MIDI.

This is a perfect blend of a traditional piano with current technology. In addition to being a great piano it also has the features of an upper end portable keyboard with auto accompaniment, computer integration and more. Read the specs for more details

Ease of Use
Turn it on and it's a piano. Easy. Scroll up or down to get to the different piano sounds. Select a different bank like Elect Pianos or Strings and scroll though those sounds. Basic stuff like recording is pretty simple. Press record and go. It gets a little complex with some of the more in- depth functions that most people might never even touch. Lots of "hold this button while pressing another button" type of thing. It works read more though otherwise you would have a zillion buttons on the front panel. Owners Manual is actually pretty good.

Key action and feel is superb! Not cheap and plastic-y but has a classic ivory like texture. On a traditional acoustic piano, the keys in the lower register are heavier and respond differently to the lighter touch for the upper end. This accurately and beautifully recreates those nuances. The instrument is relatively small and compact although not intended to be a portable keyboard. Very study and they paid attention to the important yet simple things. It has extendable support feet to prevent it from tipping in case the instrument is not against a wall. Also the 3 pedals are reinforced underneath so it is well supported. the music stand is easily removable and allows you to set a laptop in its place. The sliding key cover is a nice feature usually not found until you get to a much higher price point. The only thing that would be an improvement aesthetically is to provide a larger modestly panel like they do on the Casio PX-850 which does not have all the additional sounds and features of the PX-780.

There are other products that have similar features as far as number of sounds and other bells and whistles but you do not get in to this quality with other recognizable brand name manufacturers until a much higher price point.

Manufacturer Support
I have only had the instrument for a month or two so fortunately there has been need for support yet

The Wow Factor
When my daughter's vocal music/piano teacher came to our house, she played this instrument. She loved the sound and feel of the keys and asked where we got and what it costs because she wanted to get one for a small studio space. So WOW from me and my family and WOW from a professional music instructor!
