I've had a MC9000 since 1997 and it has never gone to the shop. Although I've had it for years, I never have actually learned to use all the bells and whistles, but hopefully this year I will turn over a new leaf and start learning since I'm not working. It is a great machine. I plan to take it in for a tune-up/cleaning, although there's nothing wrong with it. After over 15 years, I'm sure it's about time...
