I have the Skyline 9 that I got 4-5 years ago, but with health problems, I am only getting into it more and more currently and seeing lots of KZbin videos on it and other sewing things. I too leave my embroidery unit on my machine all the time. I don't think I have ever taken it off. When you took that piece in the back off, I was surprised and wondered where mine has gone off to 🤣 I love the presser foot up and down button. I have increased my sewing time by so much as it kills my shoulder to snake an arm through the throat and flick it up in the back. Who is the machine aimed for??? HMMM I got one of the first Janome 8000s when they came out. My dealer didn't even have one in the shop yet, then I moved up to a 9000. These were back in the days that I was working and had the money. I have a 300e, and have also had some machines that didn't have the embroidery unit, but when I saw the specs for the S9 I knew it had everything I wanted plus many other things to get to learn. I am 68 and it is my retirement machine and know I won't be getting anymore machines at this point. I did get a Brother SE 700 free to review for Amazon and for the price it is an amazing machine and does more than the 8000 did when it came out for a whole lot less money. Thank you for the video.
