Classified Ads Submission??

Hi,

I have launched a two website(http://www.dozentips.com and http://www.onlines2s.com) and have received a bit of success in terms of sales with both. Now I want to go out in a big way and submit my ads to as many sites as I can easily. Can anyone let me know about a good website/software that can help me submit my classified ads to thousands of websites instantly?

I was thinking about Cyberfetch Website Submitter 2.0.5. Is it a good idea to purchase that? Or anyone else has any other suggesstion?

Thanks for your help in advance...
