US 3-hole binders

[Lars Hamren]

I am seeking to replace floppy low-quality ring binders.

Where, preferrably in Europe, can I find good-quality binders:

          - Standard US 3-hole
          - "Fork" binders, not ring binders, se image.
          - With wooden spine, or other rigid type that will not
            bend or fall over.
