You made the right choice. Years ago I bought a used Bernina, and later remarked to a vintage sewing machine collector friend, "This newish Bernina has the quality of the vintage Singer's".
I recently bought a used Bernina 440QE with embroidery. I think it is about 6 years old and it is rock solid....a wonderful machine with many years left on it.
BUT, big BUT, my 2013 710 is NOT the same quality and i can't even get a really good straight stitch on it. There have been lots of complaints about the newest upper level Bernina's. After the 700 series were sold (for big $$$$$) Bernina realized their mistakes and engineered, mfg., and provided free replacement parts. Of course, these had to be replaced by a dealer, and then the tensions re-adjusted. My dealer turned out to be incompetent, so I had to take my machine to a different (1 1/2 hours away) dealer, who was willing and able to do this work. I've never bought a new machine, and i have bought many, that could not sew a good ss right out of the box. I had to invest in a straight stitch plate and the ss dual feed foot to even come close. Just beware of their latest and greatest. They are not the quality that they used to be.
In fairness, I have to say that most folks who own the 700s are happy with them, but there are quite a few who have had problems....way too many for what they paid for these machines.
