I have a vintage Elna Supramatic - the green one that folds into a steel case, and the case becomes an extension table when opened. Back then, they were all steel machines and lived up to the "swiss" legends. I don't know how they are now. They are made by Janome, I didn't realize they still used the Elna brand.
I agree with the others - if you find a new machine for $400 that has everything you want - go for it.
