Weighing in here to say I've had 3 FWs at one point but gave one to my best quilting buddy. Use the other 2 on occasion. Just released 6 machines this week to a charity quilting group ~ 3 of those machines were in cabinets. I mainly use about 4 different machines while having way too many. Despite my love for my FWs, I am in the "let it go if it doesn't make your heart sing" crowd.
To the poster who talked about not bonding with the model 66, 2 of those I released were 66s and I have another 1 possibly 2 to release along with 3 201 models. Another one I cant seem to bond with but I love the 15s.
