Power Strip with Auto-Cutoff

I live in an area where the power flickers on and off rapidly. This can go on for 10 seconds and I don't like it effecting any equipment much less audio/video/computer equipment. I know about uninteruptable power supplys but that seems like an expensive solution that just isn't needed. I wanted to know if there were any power strips/surge protectors that also have a feature that cuts power to the strip as soon as the voltage drops below a certain point. That way as soon as the power starts to flicker everything would just shut off rather than rapidly cycle on and off. Then I could just manually reset the strip when the power isn't acting up. Any ideas?

I checked out the Belkin equipment. I'm looking for something less than $20. I figure a $7 surge protector has circuitry to cut off power when there is a surge so how much more expensive could it be to design something that cuts off power to the strip when it goes below a certain level? Hmm...
