I choose the INNOVA 26 in. with lightning stitch. Get it with the lightning stitch and skip the Navigator. It is what sets the machine apart and the lightning stitch is why many people buy the INNOVA. The learning curve will be lower also and your work consistent in stitch length, sharp and precise.
As for going with the Fusion over the Avante, the fusion has a much bigger opening. You won't regret it. I did feel the Fusion is heavier then the INNOVA 26 in. and it is was slightly harder to control and get the detail for me.
