Someone gave me a heads up a few months ago that HP was bringing back the HP 15c Scientific Calculator in a Limited Edition. I quickly ordered one for $99.99 from HP's website and have been happy with it. Happy enough, in fact, to order another one. The problem is they have been sold out for months. The can be had on Ebay and Amazon for as much as $170, but I'm not paying that much if I can get one for less. I dropped the link on my desktop and have been checking it at least once a week. I checked it today and they're back in stock at HP and still $100. I'm not sure how long this "Limited Edition" will be available, so click the link after the break and order one, if you're into this sort of thing.
