I love all my machines and can't part with them to trade in when I buy a new one. I have the following:
Janome MC 8000
Janome MC 9000
Janome MC 11,000
Viking #1+ (several Vikings because I worked for a Viking Dealer, with my empl. discount)
Viking Designer 1
Viking Designer SE
Viking Designer Diamond Deluxe
Brother 300 PE (12 lbs. for carry to classes)
Singer Featherweight
Singer Treadle (inherited from grandma)
AND 2 SERGERS: Viking 2003 and Favorite Babylock Evolution Serger
I know! Sounds crazy but they all have their own personality and do different things. And to trade them in on a new machine, they only give you peanuts when you have invested so much. Better in my pocket than the dealer's pocket!
