I don't know anything about this Brother stuff. But I do know this. I have a Pfaff sewing embroidery machine that I love! It took me awhile to learn how to use all the bells and whistles and then some.
I think of buying a new one like buying a car. If I'm not satisfied with the one I have why would I buy another one of that brand.
I totally agree with WeezyRider:
If you do want another machine - go to every dealer you can find, sit down and tell them what YOU want to do.
If they want the sale, they should take the time. They should also offer classes. If they don't, then move on. Everyone here has a favorite machine. The machines are good, but all dealers aren't. So if you want a particular machine and the dealer isn't helpful, doesn't matter how good the machine is.
Life's too short and you need to make sure your money is well spent! Good Luck!!
