It depends on that symptoms the Classic II is showing.
If you got a checker board or large horzitonal bars, then the logic board needs recapping. I say recap the logic board anyways as recapping the board brings back 90% of all Classic II problems. And any Mac this old will need the caps to be replaced anyways.
If there is no video, it's the harness jack on the analog board being broken at the solder joint and other analog board problems- recap the analog board and replace the usual suspects (T1, CR1, so on...).
It would be best to do both. But for him is the expense worth it? One has to act fast before some relative forces him onto a PC.
