Flash Power


Including an Amazon link on this page is the easiest way to display the current prices, without having to keep track of it manually or write a more-complicated tracking script. And as a bonus, there's a picture of the flash. Obviously, the ad is also an affiliate link. As with all advertising on this site, I hope it's not too obnoxious.
