I bought the Janome 8900 last August. I have really enjoyed sewing on it. The extra throat space is wonderful! It has tons of stitches that are fun to use. It makes a beautiful stitch for sewing and quilting, has a lot of extra feet included. Has just about every feature that a quilter would want like needle down, built in scissors, Acufeed foot, good lighting. It is a nice heavy machine with no vibrating. I am very satisfied with my purchase. Free lifetime classes are offered by my dealer, but I haven't needed any so far. It is pretty intuitive to use and has a good manual with it.
I can't speak about any of the new Berninas. I have heard of some problems with them. I do have the older Artista 180, and it is a great machine. I use it mostly for embroidery. I've never had any problems with it. My dealer quit selling Bernina, or I would have never switched machines. I love my Bernina. Have fun choosing and using your new machine.
