Squeak_D,
I think there are a few types of keys :
a. 'Piano'-keys with real hammer-action that are relatively slow-moving and need most energy to play.
b. Weighted (non-hammer) keys, have some extra weight built-in, have a solid feel.
(sometimes called : Semi-weighted)
c. Non-weighted, non-hammer-action 'weightless' plastic keys, pretty noisy, Feel toy-alike.
d. Standard-width keys (165 mm per octave)
e. Non-standard keys (160 mm per octave)
(Yammies

)
Most of the posts I remember were about keyFEEL and not about wishes to have real-weighted (hammer) keys.
I do not like type a. c. and e. keys at all but I prefer a combination of b. and d.
regards,
Roel
