hi I am looking for reviews for Globaltakeoff. their site looks professional but you can never trust ad company without review these days... http://www.globaltakeoff.net/Publisher.aspx
I have tried globaltakeoff.net known as "globads". For me, I was wasted time and placement for about couple of week for pennies, IMHO. CPM rate is pendding from $0.06 - average $0.15. If you have a good website, you can try the link in my signature. They are good and serious and pay well with Pay Pal too, but sometimes they hardly approve sites. Give a try,But be fair and use my refferal if you want to register.
