Ad plugin/rotator recommendation

I’m currently creating a site for a client (http://dev.broadwayshowbiz.com) and purchased the AdSanity plugin, which rotates ads when the browser refreshes.

We are seeking a plugin that will rotate ads on a page ever :60 seconds or so. I know that there are image rotator plugins out there (but they don’t offer tracking stats like the advertising plugins do).

Does anyone have a recommendation for a ad banner plugin that will rotate the ads — especially one that won’t slow down the site or break the site (there are a couple out there that do just that).

Thanks so much for you help in advance.
