Free IPODs ads - where to get it

Sup guys.
I have a website that has around 1000 visitors per day (20.000-30.000 pageviews on the entire site per day). I have google ads on this website, but it is not givin much. The ads are all around the website and it is givin not more then $1/$2 a day. I was curious if anyone here knows which companies offers the Free IPods/PSP/DS ads. Im pretty sure those kinda ads are way more clicked than the regular google ads. Does anyone knows the website from those services?

 

It's the Grattis network that has become one of the more popular ones. I'm not sure if they pay you to have their ad on your website. But if you want to put my link up for either free ipod or free mini mac, I'd be more than appreciative

[EDIT] Links removed as we do not permit free ipod, free laptop etc. stuff here...it is considered spam. However, a link to actual company info as requested by the user in the first place so that he can inquire about having such ads placed on his website would be fine.[/EDIT]

Those links will also take you to the Grattis website.
