I have the LaMotte kit and like it.  I've read a number of messages from
folks with this kit and I don't think I've heard anything negative.  I got
mine from TFP for about $14.  One warning, though.  When I was using tap water
the kit read artifically high (due to something that George and others can
explain, I'm sure).  A few months ago I started using a RO unit and my tests
show CO2 to be much closer to what I expect using the pH/KH/CO2 chart in The
Optimum Aquarium.
