My AV equipment is on a plain old power strip, the strip has one of those cheap MOV thing I believe against surge but I've read it doesn't do anything. I live in a suburb in an area that has no storm to speak off. Pretty satisfied with power company, no complaint. Only my tower PC/file server is on an APC UPS because I got it free and go why not, and I attribute it to have kept my 10 years old box trouble-free and no crashed HDDs, but that's just because it makes me feel better to have to spend $50 every 2 years for the UPS batteries.
