Whatever the reason a person picks a particular machine is important to that person, let's rejoice with her when she has victories. If she wanted a Bernina_____, and was able to purchase/acquire one (legally), let's rejoice with her.
I teach classes at a Bernina dealership which stays in business by making a profit. I want to help them by endorsing their product so I teach using a Bernina machine. We give and get mutual support. When students in my class are having problems with their machines, the staff help them. Since they don't know much about other brands they are less helpful with those machines. If the machine won't cooperate, the dealership lets the student use one of the floor models, which is a Bernina.
I've had other brands, but Bernina is my favorite. I also have 2 Brothers and for their specialty, they are the best that I have. I just purchased a used Bernina 830, took it to a retreat the next day, was so excited it showed. I hope I didn't offend anyone, that wasn't my intention, just excited that I was finally able to get it. By the way, the Bernina 830 wouldn't do one of the things I wanted. I have other machines, so I put the project aside and will try on another machine.
As a sidenote, I don't finish everything and sometimes I don't intend to finish. I learned what I wanted, or got to a point that just was no longer satisfying. Why do I quilt? For the ability to create, not necessarily finish. So I want a machine that will do what I ask it, without complaining. And Berninas have a pretty good record......for me.
