Hi Liteglow,
I Imagine you can probably pick up a cube beamsplitter/combiner coated for He-Ne for about $25 US + whatever shipping costs to Norway.
If you have access to surplus equipment. Old laser printers made by Xerox or Hewlett Packard usually have beam splitters and other interesting optics within them, If you don't mind taking things apart . The laser scanner from any old HP laserjet 2 or 3 have beam splitters within the scanner.
I might have some lying around but hard to find since I moved, all stuff is boxed somewhere.
I can have a look but cost to ship from Canada won't be cheap even using surface mail (takes about 6 weeks).
