Advertisements I don't remember having a hard drive fail, either in my numerous computers or seasoned SVR-2000 TiVo. Lucky, maybe. A UPS is crucial, IMO. It's a small investment to protect your electronics. Buy a refurbished unit (usually includes new battery) and save a good chunk of money if you can't afford new. The warranty on the UPS itself is far shorter but a brand like APC should last for years, at least until the battery wears down and needs replacing or lightning makes it give up the ghost. I've bought two refurbished APC SUA-1500's, each about half off new cost, and they look and perform like brand new. A UPS offers the additional benefit of keeping your video sources and TiVo units running/recording if the power goes out.
