I use a Janome 6600P. I got it a couple of months ago to replace (or sit beside) my beloved Janome MC3500. I've had the 3500 for 11 yrs and going strong but the throat is just too small to do anything bigger than a lap quilt-and even that is a pain. I have yet to do any quilting on my 6600 but I've pieced a top on it.
