I would use on too, for safety reasons, if nothing else. You may not have to spend alot for a foot either. I have used a spring loaded foot on my Janomi machines, a generic type one I found at my LQS, for $10! Then, I got a Viking Sapphire 830, & went looking at their spring loaded feet. Theirs run $40, & guess what? Looks the same as my other ones, so bought one for it too, for $10, & it works great! It really pays to check around, good luck!...
