I brought my new Horizon home a couple of weeks ago and I LOVE, LOVE, LOVE it! My "old" machine was a Janome QC 6260 so a lot of things are familiar - like the feet etc.
I absolutely love the 11" throat space and the extra lighting. She just purrs.
For me this was a learning curve from an electronic machine to a computerized machine, but seeing as I had my sister's machine for a while, it wasn't too hard to make the jump.
My ONLY thing I would change would be the knee lifter for the pressor foot. It is too far to the right for me to use comfortably, so I just "duct taped" a 2" piece of plastic tube onto it and now it fits me like a glove!
