I bought a machine! I had three to look at at the end of May to test (after lockdown) but one of my choices went on sale yesterday. So I bought it without testing it. A Viking Brilliance 75Q. The owner uses it all the time so was able to give lots of insight and feedback over the phone. It was regular $3500 and went down to $2600. She thinks they are renaming the machine and wanted to blow out stock.
It felt right and Im very excited for when it arrives!
