I bought the Taylor K-2006 kit from Leslie's Pool Supply, $64.00. From what I have read here on the forum Ben's kit would be #1 and the Taylor K-2006 would be #2. The only down fall I can see is that the re-agents are small. You'd have to buy more re-agent a short time after you buy the Taylor kit. I'm new at this, but I've read this forum alot and the Taylor kit is what I went with.
