Is it good idea to buy a 20 years old Accuphase C-290V

Since the  current high end gears are quite expensive, so I have no much choice but to find some good 2nd gears even it might be some years of ages.  We know Accuphase is a famous brand for it's reliability. In fact, I am a bit hesitate to buy an old one like this which still cost US$6000 in the 2nd hand shop in Taipei.  How about the audiophiile's idea and suggestions?
