Well... if your machine ever goes in the shop for awhile you will have a backup machine. Sometimes they don't give you very much for a trade in too. I have quite a collection of machines. Newer model Bernina 830, Bernina 200 Bernina 1630, Singer featherweights, Singer 66-1 Redeye Treadle, Singer 15-30 Treadle, Gammill Classic Plus, Babylock Evolve Serger. Life is short.
