We know that all keyboards have + & - points. If I did not have the PSR3000 I could happily live with the PA50, it's a lot of board for the money and makes a great second keyboard with an outlay of very little in keyboard price terms. Also the 3K is the best value in the Yamaha range.
The main problem we all have is regardless how many demonstrations we attend or try out keyboards in dealers. The truth remains that it's not until you have it at home for a few days do you find all the things you don't like....then it's too late because you have spent the money.
