Hi Sunny,
I upgraded from the 2k to the 3k(and now the Tyros2)and I did't regret it.
The 3k's sounds and features are worth it.
The 3k replacement is due out next year, probably in the spring.
As MacAllcock has said, the differences between the 3k and Tyros1 are small and the T1 doesn't have smart media or USB.
Good luck,
Ian
