Alternative to Adsense on a gaming site

window.document.getElementById(‘post-3845’).parentNode.className += ‘ adhesive_post’;Hi everyone,
I am currently looking for a second ad network in addition to google adsense on my site (link in my signature). Its a gaming site with international visitors.
Some stats:
6-9k visitors per day
+-100k PI per day
Alexa: 45.814 (even if I think this ranking is kind of weird)
Visitors from all over the world, but around 80% from the US/CA as well as Europe.
Any proposals?
The ad network would have to match the following requirements:
Payment via wire transfer/paypal
ONLY family friendly ads
Any advice is greatly appreciated.
Greg
