I have a Janome 6600 which I absolutely adore. I also own 2 Baby Lock machines and Kemore. As well as several singer machines. I love them all. My advice to you is go to several dealerships and try out each brand. You will find that you will get a feel for what you like or don't. Don't let the salesperson up sale you. Buy what you are comfortable with .
Kenmore machines are made by Janome and you can use Janome parts with them. The prices are good and you will get a quality machine. I have heard very good reviews from owners of Brother machines. They are made by BabyLock. I was fortunate to get a Babylock Escape Its a travel size machine and they only made a small amount of these.
See what you like, not what the salesperson say you need.
