For the price the a1's are going for, just get a nord lead, or a lead 2x. The a1 is kind of a crappy reboot of sorts, and new features on it aren't really worth what they are asking vs. an older model. I'd love to have a lead 3 because the interface on it is really cool with the programmable infinity knobs, but I've read a few too many problems that people have had with them, so im holding off on it just for now. I did just pick up an Access Virus ti though, and it will be an awesome companion for my kurzweil. I'd love a Nord Stage 2 also, but I'm nowhere near a good enough piano player to justify spending 3k for that nice of piano sounds that no one but me will care about anyway.
