I bought Taylor's K-2006C kit from Leslie's Pool Supply. $84.00. They also have the K-2006, $64.00, it has .75 oz re-agent bottles.. The K-200C has 2 oz bottles. I think, from what I've read, that Ben's kit is best, but if you want one now the Taylor kit is second best. Compare Leslie's and Taylor's website so you can figure out what the item number is at Leslie's. The pictures are the same, except Leslie's website has a pool in the background.
