Ad Management for ASP.NET sites

I am looking out for an ad management software that will help me host ads on my website. I have checked out BanManPro but its way too costly. Google Ad manager has issues and the support system is not very active at the moment.

Has anyone create an ad management software open source that can be used on ASP.NET sites.

I am ready to purchase if the solution does not cost much.

Thanks for the answers in advance
