I’ve been debating (lurking this thread) about the same thing. My plan is to sell the A4 and Indigo 2. Then replace both with the AK.

  1. I don’t use the Indigo 2 as much as I should. I had the motherboard replaced not long ago.
  2. This would save space and simplify my setup.

I’m not sure if I’m thinking rationally. I should probably not bother.
