Don't know about the Telequipment, but I own a Hameg that is even 
older, a HM412. It needed one major repair once, the high voltage 
secondary winding of the mains transformer was broken. I have heard of 
other Hamegs that had that issue too. It also needed a smaller repair a 
longer time ago, but that was only a zener diode. Otherwise it works 
still fine and bright, but I haven't used it very often.

250 Euro seems a lot for a used scope to me. You can get a new dual 
trace scope for 300 Euro from Conrad for instance (not a Hameg of 
course). But when I had that mains transformer issue with my Hameg I 
looked at Ebay too for used scopes, they are indeed quite expensive.
