I have a PR2 Polling site, APopularityContest.com that has been around since 2006. It averages about 8,000 uniques a month, and gets about 15,000 page views a month. The space has been filled for over a year, and is now finally open. Rates are $9.95 for one month, $16.95 for two months, and $19.95 for three months. You can order the space, and see where the ads go as an example here: http://www.apopularitycontest.com/advertise.php You can send me a pm if you have any questions. The map overlay does not reflect it for some reason, but it's about 70% US traffic, some Canada, and some Australia.
