I agree, the Open Labs keyboards are basically a lot of nothing.....I am interested in the Mediastation in the future but only once I will be certain that it fulfill my needs: I want it to do everything that my PSR 3000 does, out of the box.

Might seem ridicolous, but I am not so certain about that. I find the PSR3000 a great little keyboard for composing, so for now I'll use the PSR. Once I've got the midi file out of the PSR, I just transfer the file on my PC and substitute all the sound with Eastwest library (and these sounds just can't be beaten, although they are not strictly necessary to sound great)

I also don't want to buy more than one keyboard,....if it works for you , great, but really , the Liontracs should do it all....to use two keyboards at the same time is a bit overkill, and it's also not budget-effective.

But yes, if money were no objection, I'd probably go for a similar setup as yours or Vagro's....if it works, it works.
