Update!! I was able to see the Innova sit down at a show yesterday. They've modified the design for the regulated machine so that the big regulator block is no longer just above the needle. The sensor is now under the acrylic insert that encloses the base of the machine. It senses the movement of the fabric over it. They also put it in a smaller non-furniture table which results in a lower price. The table is bigger than the HQ Sweet Sixteen although there doesn't appear to be any option for leaves.
What a beautiful machine. It works beautifully.
I ended up getting the Babylock Tiara (just like the HQ SS). DH suggested that I seriously consider selling the Tiara while it's near new and get the Innova. Tempting but not sure I can justify it.
But thought I'd post on my impressions and the changes they've made in the machine and setup.
