$16.50 shipped (well to my zipcode) and they are sold as is (could be some bad disks).
Ask around on lemswap for a set and see what replies you get. I prefer to spend as little as possible, and give that money to people in the hobby and not the business of computers. Ebay has its place for rare items you will never see, but lemswap and forums are great for common items at a decent price.
