The M-Audio Keystation 88es arrived today.
I haven't hooked it up yet but I have tried out the action. It's the first non-Hammer-action keyboard I've used in five years and so it feels really light. They call it semi-weighted so I'd hate to feel non-weighted.
But for $250, it's worth it and as a colleague just pointed out, I have 88 more keys than I did yesterday :-)
