I've used Tetra, Dupla and Lamotte test kits and prefer the Lamotte by
far.  The initial cost is more usually due to the color comparator,
but refills are very cheap.  

Having said that, I still prefer the Tetra KH and GH test kits for
hardness.  The KH kit agrees better with theoretical values obtained
with CO2 and pH readings and published KH/pH/CO2 charts than does the
Lamotte alkalinity test kit.
