My view may be a bit different. My plastic toys have been earning me many dollars for years, and more than most – and I have had no mishaps for the last 16 years.
If there is a need for strongly built keyboard to do your work that’s good, but it is not necessarily related to the quality of sound, longevity of the keyboard or the amount of dollars you can earn.
Is a 4,500 keyboard better than a $2,000? I would be shocked if it were not. The question is – better in what ways – and then I am I in need of those features.
