On "dirty power," it can be an issue if its really bad.

Father in Law retired to a small town, population about 3000 with really dirty power. In fact the power goes out often enough that he has a generator for his house.

Anyway, he has a 52" Sony rear projection tv and the bulb burned out every 6 months... and they aren't cheap.

Eventually he got a large UPS and has been fine ever since.

Having said that, yeah, most of the time its a non issue. This is a really small town with bad facilities.
