Like others have said do some research. I have a Janome Memory Craft 9000, 3 Singers and a Bernina 440QE. I have to tell you that the Bernina is a far better quality machine. Even the straight stitch is unbelievable. If you can take the time to try them all it would be good.
A friend has a Viking that she paid over $5000. and she has it in the shop more then home.
Several years ago I also had a Baby Lock. But was very poor quality and sounded like a bunch of tin.
Every one has their preference and mine is my Bernina. I would trade my husband before I would let any one take my Baby B.
Good luck, Karol
