I of all people should have learned by now. Here's my situation, I live in a basement with my fiancee (we're saving to buy a house of our own) and we have a main power outlet hanging from the ceiling, we then have a heavy duty outside extension cable with 3 prongs from that outlet going to our wall-o-entertainment (computer, gadgets, tv, theater, amp, etc) and a surge protector plugged into that, the comp and it's accesories are plugged into the main surge protector, which cost like 80 bucks new. then on top of that, we have a secondary surge protecter, cheaper and smaller but the kicker is that we just bought a new space heater and had nowhere to plug it into, so we stuck it in the second surge protector, the lights dimmed just a little when it kicks on, thats normal, but finally, i had it set for two hours and poof, no power, i thought it was the breaker so i check it and flip every switch and nothing, then my fiancee reminds me that there is a breaker on the main surge protector, phew!!!
anyways, moral of the story, when you buy a surge protector, buy quality and do not overload it by stringing another power strip onto it.
