I should mention, I usually use 10 seconds. I never have a technical problem placing my bid in time and thats enough to keep anyone from making a bid based on mine. Thats all sniping really is is cutting things close enough to keep people from bidding it up on you based on your bid. If everyone used sniping then the person who truly wanted it the most would always win and emotions about not letting that other so and so beat you would never enter into it.
