Which M-audio keyboard (midi controller)

[Trifid]

Hello.

I want to order a midi controller but am unsure what the difference is between these models.

M-Audio Keystation 61 ES £124
M-Audio Oxygen 61 (Third Generation) £142
M-Audio ProKeys Sono 61 £201

From what I can understand, the 61ES has a single non-adjustable velocity curve that isn't very good. After this I am lost between the differences. Does anyone know what will be best for me? I want to use it to enter music into Logic to play along to.

Has anyone recently bought one of these that can advise?

Thanks.



Edit:
I think I have worked it out, The ES is a midi controller, with no built in sounds but semi weighted keys. The Oxygen is the same but with non weighted keys (which will mean playing it as a piano will be very poor instead of just not as good as a hammer action) and so more suitable for synths and so on? the Sono is what I really need, semi weighted digital piano with midi.

Can anyone confirm?

Thanks.

Thanks for your replies, however I've already gone for the Sono and should be with me tomorrow. It was more than I really wanted to pay for its purpose but wanted to get something that was suitable. I'm not bothered about the sliders (what are they for?) and hammer action (am not playing it to learn the piano as we already have a proper one in the house). Just need it to play sheet music into the PC but wanted a good velocity curve to stress accents and for dynamics.
