My first comments about the 2000 were the very cheap cabinet, key and button construction. I use mine at home and I do not bang on the keys or the buttons. I have learned from being a computer geek that most computer components need a sensitive touch.
Having said that, the keyboard under pro use should not break within 6 months. Its supposed to be built to play as an arranger keyboard with all the inflection on those keys and buttons as you need. While I do not play it like a piano it doesn't change the fact that most do.
If it was not meant to be played by an experienced user, then there should be warning signs in the manual and a sticker on the keyboard. There are none, but it should say:
***WARNING KEYS AND BUTTONS SUBJECT TO BREAKAGE UNDER NORMAL USE***
