This is the only keyboard that gives me a slight boner nowadays, but I probably wouldn't buy it...

I am definitely with Bob on the weighted key comment (especially the "speed limit" with weighted keys). Semi-weighted with the ability to tailor the velocity curve is more versatile. I started out playing piano, but have readily shifted to soft synths and a MIDI controller. This is obviously a matter of personal preference and playing style. 

Go to the store and play a bunch of keyboards.
 
I bought Kurz PC3x on impulse and regret it. I do not like the Fatar action. I am going to sell it and get a Kawai VPC1

Old thread.
New keyboard.
Got myself a MODX8.

Lovely bit of instrument... huge sound... does have GHE action or Balanced?
