I have a Koala cabinet for my SM. When using my Janome, I had an acrylic insert. My Janome isn't working now. My GF gave me a Husqvarna 500 and the insert would not work with it, so my DH made me one from a piece of masonite. I think it will work just fine...and of course, the price is definitely right compared to paying for another acrylic insert.
