I have the Janome 11K. I love it, had one problem after a few months, but they fixed it right up. I use it mostly for embroidering. Do my regular sewing on the Janome 1600P. I too have not used the quilting part of the 11K, just having too much fun with the embroidery, so quilt on my 1600P which I call "The Beast". Because it is such a work horse.
Mine was on a terrific sale also when I bought it. It's not quite paid off yet, but figure at my age it was a good thing. I used my Janome 9000 for 13 years, so I was due to get the new one. :)
