Cyndi, I guess I really didn't understand the need for more than one either. When I bought my Janome I traded 3 in and one of those I will always regret not keeping.
I called the sewing center in the area and the guy has the foot control for the Bernina but of course he has a list of reasons why I should just invest in a new, inexpensive machine from him. Can't get parts, going to have more money in it, etc. I told him I wanted something that is going to take really heavy things when I need it and he then told me to go ahead and give it a try.LOL

Neither of the people have gotten back to me so we will see.
