I want to sell off my PSR-3000 for a beter alternate.

Please comment on the following:

1. Tyro 2 or S900 or Tyros 3. (If price is and is not an issue)

2. What are the equivalents in Roland and Korg and how are they in comparison.

Seeing roland and korg sites, some of the features shown like touchscreen, scratchers, sliders, 6 voice layers, multiple simultaneous mp3 playback and recording and what not are present in most of such keyboards and these are still absent in Yamaha. Moreover they are slightly cheaper than tyros, but only slightly.

What I wish to know is how the tyros 2 or 3 compares in front of these keyboards. Seriously, the top roland and korg workstations beats yamaha motif, as appears from their demos.

I am a Yamaha lover, and using it since 10+ years and would like to stick to it. Hope Tyros 3 comes up with such classy features.
Please advice as to what to buy and when.

Thanks in advance.
