I've had two Vikings and about two years ago, I purchased a Jamone 9000 which is my primary machine. It is a very nice machine but wish and wish I hade purchased another Viking. (Both of the Vikings are still in use; one is set up all the time and the second will be up when I start 4H again).
I think I if were going to invest in another machine, I definitely would have a stitch regulator AND it would be a Viking.
