I'm a fully paid up coward. Lamp limiter and/or variac every time. Except for kit with switchmode power supplies which can do nasty things.

I remember the late and much loved Gerry Wells never took any precautions. The odd bang was all part of the fun, though I think he said he once had a main electrolytic explode through the case of a radio.
