The Taylor K-2006 is a great kit. I would also recommend that you buy an extra DPD power and the CL reagent at the same time as the kit and the CYA reagent. Saves on shipping. Buy the largest CYA (16oz) and the largest LC reagent (1.5oz, I think). The DPD come in just one size. I got my K-2006 at the beginning of the season and CL is definitely to test that I seem to perform the most. This site also has good pricing on test kits and reagents. http://www.poolcenter.com/Chemical_testing_in_pools.htm

Since you said that you have an SWG, you may want to consider a salt test kit as well. The salt test strips are pretty good. Although test strips in general are not considered very accurate, the salt test strips are one that I have found that seem to be very good.
