I think in the long run the LaMotte kit would be a better deal.  I 
tried the SeaChem kit but couldn't get good agreement with standards 
I was making. I recalculated and remade these standards several times 
and still did not get good agreement.  I bought the LaMotte kit and 
got goood agreement with my standards.  I also found that my aquarium 
was about 50ppm nitrate not 5 as I had been reading with the 
SeaChem kit.  No wonder I was having an algae at the time. 

I think the problem I had with the SeaChem kit was my ability to 
compare a color intensity using a cardboard chart. The LaMotte kit 
has a comparator that uses vials of colored solutions that makes 
judging the color intensity of the test vial very easy.  Note the 
refills for this kit are about $15-$16.
