If you buy the Talyor 2005 - it'll have everything you need. If you have a Leslies Pool Supplies they sell the same kit with their name on it.
Last summer I bought a test kit in a nice blue storage case at Walmart for $14. Has pH, TA, CL and hardness. Works great and when I need new reagents they send refills to me for free. I've had reagents replaced twice now.
