Scott,
excuse me, but your thinking about upgrading from your psr2000 to another kb, XD9, which costs (I think) exatly the same price on Synthzone.... makes me think!
It is clear you think XD9 is better than PSR2000, but its price is similar.
Do you think PSR2000 it high priced so?
By the other side, you doubt between Tyros and XD9, but Tyros is much more priced.
So, it seems as you think XD9 is a great choice for its price, and Tyros is good but not so good for its price... Am I ok?
