I've mostly used vintage machines older than I am for the last 30 years or so. This past fall my friend gave me her replaced modern Bernina 820. She simply did not click with the machine and bought herself a different Bernina, because it is her favorite brand. She loves that machine.
So I have nothing to go on in comparisons with other modern machines but I just love Bernie! It has an extra large bobbin, huge throat space, a self threader, and a knee foot lift (which my friend never used but I do it all the time). At first I had to struggle with myself to use the modern features but I've quickly gotten used to them.
The 820 had a lot of negative reaction and they stopped making them fairly quickly. My friend's machine had no real problems and while not right for her, has been excellent for me.
