The only decent traffic you can pay for is either by advertising on a high traffic relevant site or using google adwords or yahoo search marketing.
Those companies that offer 100,000 visitors for $50 are simply ripping you off. Pop up, pop unders or redirects do not work no matter what they tell you.
If you don’t want to pay use SEO the raise the rank of your site.
