You've paid way too much for that N900. This kind of things is much better to buy from local store or local online market (eBay like site).

3 months ago I bought N900 (box, cables, manual book, cover case..perfect condition but with broken ribbon),
paid it 40KM (or €21) + €5 new ribbon = €26

I bought it at www.pik.ba, where most expenive one cost about €100 (195 KM)

I do believe there is similar site in Greece too.
