I have an A-300pro by Cakewalk (now by Roland AFAIK) and am very pleased with it. It's integration with Sonar is near perfect.
The other thing I like about the A-300 is the number of keys. It has a few more than most small controllers that, I find, makes it a lot more useful.
I guess that should have been obvious! So I guess its fair to say for easy compatibility out of the box, this series is the way to go? I like the form factor of the A800PRO, it would fit the space I have better, although the compromise is travel / size of the controllers. I'm not too keen on the stick either.
I've got this thing in my head about going for a semi-weighted action, but I'm in two minds. I tried an M-Audio Keystation, its the only semi-weighted action I've tried, and it was horrendous. Not like a natural piano action in any way, it worked against you, so light playing became difficult. This is the opposite of what I'm looking for, I want something that enables a light touch. If this is what all these 'semi-weighted' actions are like, the Roland could be a real contender, because I know I'm guaranteed a good playable synth action.

if action is of a concern, I think you would be better off with a used Novation SLII, or even SLI if that better fits your budget. The keybed in the SLII is from Fatar and significantly better than either of those you mentioned.
Its a little over budget, but if the action is really special I could maybe save my pennies. Only thing is the stick again. So with the Novation, and Automap 4, can anyone confirm that if I set up Automap 4 following the instructions for Sonar X1 (which reading other posts is what you need to do) I'll get good reliable and permanent control of transport, faders etc, thats comparable to say the Roland series mentioned above?
I'm leaning toward Novation but I don't want to get stung by poor integration with Sonar X2. I can live with reasonable but not perfect integration, as long as it is consistent and the basics are covered.
