Sorry, I should have made it clear. None of us have seen a K-2006 for sale retail, it's really only available online. If you log out then navigate to the "Pool Water: Treatment, Testing & Problems (P)" forum and then open the "How to Get the Right Testkits for your Pool" thread, you'll find links to the kit at amazon. If you buy through those links, the pool forum gets some cash to keep the lights on.
Your local wall mart may carry the HTH 6-way drops kit (not strips). This is a decent kit to get started quickly but not a replacement for the K-2006.

No need to be nervous. You've found the right place. With the right tools and the information here, you'll be in control of your pool in no time.
