Today I finally bit the bullet and bought a new sewing machine - a Janome 8200. It was the only one of that model at the store and I gave it a bit of a trial run there. The woman at the store was more interested in showing me what it could do, but did let me play a bit. I'm not happy with the button holes she made, but I'm not sure if she had everything engaged. Hopefully when I play around with it, using the manual, I'll get better results.
The machine is huge! I'm going to have to rebuild my table if I want to use it on a level surface. Here is a picture of it (accessories all out) next to my old machine!
