Apparently flipping a light switch etc. in your house makes it go completely nuts. I am contemplating on purchasing it and I'd have to leave a fair offer on the table.

I couldn't advise on $ or possible fixes, but if it were me, I'd assume, say, a 50/50 chance it dies in a few months, and offer accordingly.

Zero, the same I would pay for an old car that stalls at stop lights occasionally.

that's something where I wonder if a beefy power conditioner will "protect it"... but then you're spending money on an ad-hoc fix that might have been spent on buying a non-broken item

It could be as easy as moving some cables inside back to their intended position or reterminating them --> cheap and easy fix. To the sour end where an IC might be damaged and is obsolete or otherwise next to impossible to replace.
It does smell like a bad cabling issue, or some capacitor might have gone.

@wbass That's actually a very good point! There's certainly some risk involved, since I cannot really test the unit before buying it.
