I have a green Elna a little different than yours and I really like it, has the great little Elna growl, sews beautifully and powerfully. My only problem with her is the knee press. In order to use it you need a lot of space to the right ( like setting up in the middle of the dining table) and you have to have the machine centered differently. This threw me off because I sit at my machines with them at an angle and I couldn't do it with the Elna.
Aside from that I loved the Elna.
