I think I would buy a new Janome, they will show you how to use it, can take lessons. Well worth it! I bought my last one used from a friend, while it is a dandy of a machine, I wished I had just bought the new Janome like I had intended.
If you don't want to spend that much, there are good used ones out there at garage sales, craigslist etc. A lot of people buy them and hardly ever take them out of the box.
