If you don't want to order Ben's kit and wait for delivery (and believe me, the wait is well worth it!) then the Taylor K-2006 and also a K-1000 would be the ones to go for. If you get both these kits you will have the same functionality as in Ben's kit, most of the reagents are interchangable, but the K-2006 has a few tests inluded that are of little use (acid and base demand), and the pH reagent is different, hence the K-1000 which also gives you the OTO test for Totol Chlorine (very useful!) . Also you will get fewer tests before you need to replace the reagents in the Taylor kits. The CYA reagents included in the Taylor kit is only enough for about 5 tests! Ben's kit is a much better 'bang for your buck!".
