Need a midi keyboard with good feel of keys/keybed

I dont need all the knobs and controls, if it has that thats fine, but what brands have the best, natural feeling keys? I need something that feels good to the touch while playing, no mini keys either, I need something full size keys with at least 4 octave range at least preferred.

I know M-audio makes those basic key stations but how are the keys on those? and anything better?

Also something thats plug n play quick, or easy install

thanks for reading, feedback appreciated

Axiom pro 25/49/61.

I have the 49 (semi-weighted TruTouch) keys version wich i use with my MPC and also as a generic MIDI controller in Cubase. It has a very good feel of keys/keybed. I def recommend it.

M-Audio Axiom, I had one but not the Pro version.

I agree with the Axiom. Pretty solid keyboard with semi-weighted keys.
