Tough one as prices in Holland may be a little different to here, but in U.K. probably between £500 and £1000.... I have left it broad as it depends on the day and many factors like condition, completeness, operating function etc... Again in US prices vary, they seem to demand better prices there.
Geordy55 google translate is very usefull. My son showed me yesterday google translate with the camera of his phone. Hi pointed the camera on his English books from school and you will see the translation on your screen exactly the same colours and type of letters.
