About 3 years ago I bought a Berninia with a stitch regulator and an embroidery module which I haven't used. The day after buying it I wanted to return it, but the dealer wouldn't let me. I think my investment was close to $3,000 which was huge for me. Slowly I have adjusted into accepting it. Part of it was change, the other was expectation. I missed features I had on my Viking such as no bobbin case, bobbin filling without re-threading. I was disappointed in the inadequate space for quilting, the performance of the stitch regulator, and hated the awkward bobbin system. I have learned to live with it.
I did not do my homework! I got sold by a slick salesman, and by watching TV shows featuring this brand. Basically I was stupid.
Keep getting information about the machine, use real fabrics when you test it not those starched samples. Look at the costs of supplies, accessories, servicing.
