Fatar TP40/L: where or alternatives?

Hi folks,

My fingers have been always at ease on the kurzweil keyboards i had so far, which sported a Fatar TP/40 L (Light, 45gr). I loved it because I could get most of piano expressivity but still be able to play organ/synth parts with relative ease. The problem is the schlep factor (never under 20kg/45lbs..), so i'm trying to find more lightweight alternatives.

Is there a list of keyboards with the TP/40L somewhere (the ones you find on google are usually out of date or just say 'TP/40', which could be 40GH for example)?

Or, is there any tp/40l aficionado that found something else that satisfied them?
