Popunder script that cannot be blocked (NO layer ads!)

Hiya I would like a POPUP SCRIPT that is Very, very hard to block by popup blockers. I don't want fly in ads or layers ads. I need a window .open REAL popup or pop-under window. The normal popup codes are blocked by 95% of users. When you have something which is blocked by 30%-40%, it will help a lot. Max plan for the code is $30. Give a sample of site where I can tell if it's working. Send me a message with the example In case your popup code doesn't work, no payment obviously. Payment made by Paypal Thanks.
