thx guys i will have a look.
i have asked at local stores specialized in camera gear and to be honest, they all suck.
first, they have no cameras in their stores, beside cheap P&S cameras.
but they can order them (well i can order them myself and have it a day later delivered to my doorstep).
second, even when they had... they would not rent it to possible customers.
i don´t know how they manage to survive with all the competition from media markt, saturn and co. but i guess they will not last much longer.
they are more expensive and they don´t offer support that´s worth paying a bit more.
