Having owned two PSR-3000 I must say it is a powerful keyboard and is the equal of the Tyros1 in my opinion.
The Tyros2 is a different matter...it is light years ahead of the 3k(and T1) in terms of keyboard action and the SA voices and extra Sweet voices are definitely a cut above the great sounds in the 3k.
I enjoyed my time with the 3k immensely,and I still have one as a backup, but once I began playing the Tyros2, there was no going back.
It was well worth the difference in price and I have no regrets in making the purchase.
Remember to leave good news alone.
