I bought mine for 80 euro's at the largest electronics fair in the Netherlands. It was 120, but nobody wanted it. At the end i offered 80 and that was accepted. Came with a new matching probe too :). It missed some buttons and one of the input attenuators was toast. Got the attenuator and replaced all caps. Instead of finding buttons, i bought the whole pannel with the buttons from a supplier in Israel. Obviously somebody missed the that part with the hammer...
Still have the old pannel and it has the three largest buttons. The sec/dev is not completely straight, but usable. Give a shout on what you find.
