I have an APC UPS connected to a APC surge protector.

Lightning took out two very expensive Ascend routers of mine a few years ago and I vowed to never let it happen again. Afterwards, I put redundant power protection on everthing and am proud to say nothing has been damaged by surges since. Here in E. Tennessee, we get some pretty sudden and intense lightning storms during the summer and I always hear horror stories of how peoples stuff get fried.
