$20 through PayPal for two weeks (14 days). That'll give you a total of 70,000 unique views to your banner or link.
I don't do rotating ads, only one ad for their paid time in the order I receive them... so your ad will be the only one on the page, never rotated out, and placed just below the "Upcoming Releases" link on the frontpage, centered.

I'll place ads in the order I receive the payments. So if three people pay, I'll place the first ad for 14 days, then the second for 14 days, then the third for 14 days. As of this posting, there is nobody waiting to be placed on there, so the first payment gets their ad up tomorrow.
