I think its still a better buy than the 907 limited, the sansui is a pretty old model, no cd inputs yet, the sony is the better choice, but i didn't get the chance to test the unit myself. When I opened the unit, everything is squeeky clean, which means na may na repair na dyan, that's why i got curious and looked more closely. The sansui I got from the same store still has makapal na alikabok inside, which is a better sign na di pa kinalikot i think. test the unit, if you like the sound, then its a good buy. I saw mga 6 or 7 resistors changed sa right side na pcb, the repairman said he changed the old ones with compatible resistors, malamang same resistance, so it should be fine. I noticed another thing, sa may speaker connector sa loob, there's one square device na parang napalitan na, 2 kasi yon magkatabi, yung isa plain grey in color lang, yung katabi nya nanduon pa yung brand, not sure kung napalitan din ito.
