The 741 op amp is VERY common, probably the first opamp that a lot of people come accross in schools, im sure you can get one in sweeden, I dont know what sort of electronic shops you have over there but any electronic shop should be able to get you one (they arnt expensive). You can get a bit more info here http://www.national.com/pf/LM/LM741.html
Next time you wave, use all your fingers.
