Best fuses for under $50?

Nonoise, to be sure it’s clear the caution I was expressing just above pertains not only to avoiding the possibility of blowing a fuse, but to avoiding the possibility of other damage to the equipment, or degradation of its long-term reliability, that may be much more serious.

I make a point of not even turning my computer or TV set on for at least 30 seconds or so after turning them off.

I tend to blow one once a week if I power it off and on again too fast while messing with connections.

This is what happens to a fuse over many switch on surges. Same fuse 5 different ageing periods, it hardens, carbonises, distorts it’s straight (new) shape because of flexing and will blow in the end.

I would add that depending on the specific design even a brand new fuse might blow if a component is turned on too soon after being turned off. DC voltages that are supplied to various parts of the circuitry may still be in the process of decaying, resulting in uncontrolled and unpredictable behavior if the component is turned on while that is occurring.

IMO it’s never a good idea to turn any electronic component on until sufficient time has elapsed from when it was turned off to be confident that all of its circuitry is no longer capable of functioning in any manner, controlled or uncontrolled. That may mean a few seconds or a few minutes, depending on the specific design.
