I would have waited for the new machine over the A4 Keys but I spent the money I had on a black Friday deal on an Octatrack. I needed a sampler a lot more than another synth or mystery machine, but they got my money anyway.

I would suggest to anyone with this dilemma to just wait and see what the new machine is. I have some bad gear lust so I understand. But just wait till all of your options are in front of you. You will make a better decision and feel better about it without the guessing and possible regret.
