I have the T4 and love it! I would like to see/hear the PA3X 61 keyboard, although I wasn't crazy abt my PA2X. I had 2 of them, both with LED probs + I didn't really care for many of the styles.
The only regret I have is with the Audya 4. It just doesn't suit my needs. To complicated! I'll sell it soon, and consider the Roland BK-7m!
