You may have issues with setting it up as a controller with Reason 10. Just really wanted to know anything good or bad about the Arturia one. At the moment I’ve got a 37 in the desk and a full size electro piano on the side which also serves as a midi keyboard. Reason for wanting the 49 is so I have room on my desk.

But again I haven’t seen them in real life. Just seems straight forward with no frills and good build quality. Kind of trying to avoid that and that was the main reason I was looking at the Arturia. I took a quick look at the ones you mentioned and at first glance, and this is without seeing them in the flesh, I thought they looked a bit “plastic” and too many flashing colored things. However, why don't you go for a 61 key solution? Only a little more money and a bit less octave switching.! You'll never get a better synth type keybed and the integration with VSTs is top notch. For me the latter is head and shoulders above the others. If you are talking about the Keylab rather than the Keylab Essential you should be weighing it up against the Novation SL MkIII and the Komplete Kontrol S49.
