All Personal Recommendation Banners
On some pages of this site, a banner appears in the left-hand sidebar, advertising a website, service or product that I've used personally. I only use this space to advertise services I can recommend from first-hand experience.
Those banners rotate at random. Sometimes, people see an advertisement, but next time they visit the page it's been rotated out of the way. If you wanted to review any, this page contains all the banners, so that you can find that one you're looking for and click on it if you wish.
