Really? Which ones?
I've tried them all -- Akai, Alesis, Arturia, Behringer, Korg, Line 6, M-Audio, Nektar, Novation, Roland, Samson -- and, to me, none of them feel "pretty decent." There's always something wrong with them: too tightly sprung, too spongy, the pivot point is wrong, the keys are uneven, it's too difficult to get a good velocity range, the keys are too short, the keys have rough edges, the key travel is too shallow, etc. And that's just the keys; there are plenty of other issues with build quality, knobs and sliders, wheels, drum pads, etc.
Makes me wish I'd kept my MIDIBoard! However, I had to deal with a really buggy OS and sold it quite a few years back.
Anyway, the action of a keyboard makes it or breaks it for me. Sure it would sound good, but what's the use if it isn't playable? I had such a hard time with my church's Ensoniq KS-32 over a year ago, that I had to start bringing my own instrument (Quadrasynth.) Haven't touched the KS since.
