Dutch or German Electrical stores

Well -- Our trusty 40litre microwave combination oven has died after very heavy use for a good few years -- Best price I have found in Belgium for same model is a shade short of €400 - whilst it is under £200 in the UK!!!! So before I do a day trip to Folkstone -- can anyone advise an electrical store in Netherlands or Germany that also shows what they sell with prices online? (NL and DE is a lot closer for me)
