@dec_hl I’m not sure about the price but I can recommend Bernina. My first one was a gift from an elderly aunt, had been her wedding present 60 years earlier, and it was still perfect. I bought another Bernina because I wanted some modern features and it’s been a lot to use for 20 years, no issues, a beautiful machine.

@dec_hl ich habe eine Smarter by pfaff 260c
Die hat nahezu alles was du suchst. Ich fand sie beim ausprobieren viel leiser als die Brother Geräte. Sie hat auch eine regelbare Geschwindigkeit die entweder per Pedal oder Knopfdruck läuft. Zwillingsnadel hatte ich keine Probleme. Großer Vorteil: die unterfadendspannung muss nicht eingestellt werden.
Zwei Lagen Jeans sind okay

@dec_hl Looks like the Husqvarna Viking Emerald 118 I bought a few years ago, after reading a lot of overwhelmingly positive reviews (eg. https://www.artisanstitch.co.uk/best-sewing-machine/), ticks almost all those boxes, the exceptions being:

1. The light is a W5W incandescent bulb, but can be swapped for an LED equivalent.
2. The reverse lever was a constant annoyance, but was pretty easy to fix with some scrap plywood and M3 bolts, so I can now operate it with my right palm, and effortlessly alternate between forward & reverse.

@dec_hl one thing to add, is that the presser foot hight/tension could be adjusted. Sometimes it makes difference with the feed.

And easiest model to keep in functional form is the one that has service around your area. (Unless you service them yourself, of course.)

PS right now I have a fully mechanical "W6 WERTARBEIT N 1235/61"

@dec_hl Elna sewing machines are very good! cannot remember which models have automatic thread cutter (if that's what you are looking for) but worth taking a look
