Mirian:
Keep in mind that generally text links will get much better results. Surfers just don't respond as well to banners anymore. (but if you do use a banner, at least put some descriptive text below it)
I especially like the rotating java text links provided. The text changes according to whether it is work hours (9-5) or after work (at home with the family) in that person's time zone.
As for the CP, Beasty, etc sites, I'm sure you're probably right that such people would be more inclined to buy such a product, but I have no way of verifying that...anyone got Michael Jackon's email address?
