When the Bernina Artista 200 came out, years ago, I purchased one on the first machines. I hated it! It was in the shop more than in my sewing room. It took three years and lots of upgrades; but now I love, love, love it. It has been a dream machine once all the bugs were worked out. When the 830 came out, I really wanted one; but did not want to go through what I went through with the new 200. I think Bernina puts new machines on the market before all the bugs are worked out. Once they solve all the problems with a new machine, I agree that nothing sews like a Bernina. I hope you can work out a good trade for your machine or that the problems can be fixed.
