Thanks for your advices!

As far as price$ are concerned, i've restrained my list to Nord lead 2 or virus classic...

BUT, I will certainly take a look at the novations, and EX-8000 i've never heard either of them...

Korg DW-8000? I've owned a DW-6000, but wasnt really into programming at this time, i basically gave this keyboard... Maybe i should have kept it!

THanks for all suggestions, they are really helpful... Bottomline, 3351 is right, try them is the best way to choose
