A piano is not a commodity or a necessity like a phone, computer, food, gas, vehicle, apartment or house. A piano purchase is using your discretionary income, so you could make a choice to live without it. However, if you or someone in your family is anything like me (or my students or children) when it comes to listening to or playing music (incl piano, keyboard, guitar, etc) then it is something which can be difficult to be without, and I know many other people who feel the same way. It's also one of the best things you or a family member can do for yourselves or your children physically, mentally, and spiritually no matter what age you are!
Also, take a close look at the new Casio Privia PX850 and PX780 (above left pic) which I recommend in the lower price range that can be seen at the following links on my blog reviews:
