In this post I compare the Taylor K-2006 against some test strips. There is really no comparison in resolution nor accuracy. Also, as Ben mentioned, the K-2006 uses a FAS-DPD chlorine test that does not bleach out at high chlorine levels the way the DPD test does and it is more accurate to within 0.2 ppm for a 25 ml sample size and can even read up to 50 ppm (using more DPD powder). The less expensive DPD chlorine test that is read visually only goes from 0-5 ppm with roughly 1 ppm accuracy though even that's a stretch.
