Maybe you will get more easy trafic and cheaper by exchanging links with quality pages. At the moment for example we search link partners with: UK Domain Names Uk Web Hosting
I am quite sure that is a cheaper way. Especially if you exchange this links and don't buy.
When there are plenty of Free methods available on Internet to drive thousands of traffic, why would anyone opt for paid traffic options. I believe that SEO is the best method to drive loads of traffic to your website for free.
