I wanted a Bernina for years before I got one and I've loved every single minute of it. The only problem is that I've gotten interested in FMQ and my Bernina doesn't have the throat space so I bought a mechanical Juki that I absolutely love!
I have several vintage Singers as well. I especially love my FW because it's so portable. If I feel like sewing in the kitchen I can.
I like the modern features of my Bernina and Juki but also love the old Singers. They are all fun to use.
One thing I've never been able to get used to is the knee lift. Mine doesn't get any use!
My very first machine was a Kenmore 1030 that my Dad bought me when I had my first baby. I'll never part with it. It still works but I don't use it much anymore.
