I love my Janome Horizon but I did have a major problem with it. Something went out on the circuit board and it took about 3 months to get it back. Haven't had a problem with it since. Luckily, my dealer loaned me a Horizon while he had mine. I think I was one of the first to get mine so they probably have the problem fixed now on the newer machines. I also like the larger harp (wish it was bigger) and the knee lift. I am going to have to try the stop-go button. One reason I bought the Horizon is because my dealer gave me full value on the 6600 I bought from him a couple years early. I do miss being able to wind my bobbins while sewing - something the 6600 does but not the Horizon.
