Update - I brought my old Elna to local sewing machine shop and it seems that part was broken and now obsolete. I was actually quite pleased to have a chance to buy a new one as I weighed the old one and it was 12 kg!
The man in the shop was great - good choice in stock including the Janome brand I had been considering. He showed me a few, giving me a chance to try them, and I was able to play around with them, testing the different stitches and settings. I considered one of the Janome ones, but it was all electronic and he suggested I try a Husqvarna. It didn’t have as many ‘bells and whistles ‘ but was more similar to my old Elna, so I went for it. Model - Viking 116. Mid-range machine, does everything I need and copes with heavier fabrics.
So far I’m happy with purchase, as also with service in independent shop, as suggested by a few other posters. For some things, personal service is better than buying online.
