I have two Janome's (have actually had 4 and have updated). I now own a 6600 and a MC1000 and love them both. I have a round flat screwdriver that is also great for arthritis. Absolutely wonderful - you will love it. Makes getting to those screws super easy. got it from Morko Products.
[email protected] on line and order from there. Best small screwdriver for machines I have ever found and I also have short screwdrivers - this beats them all to pieces. From Amarillo....
