So far, I've used Seachem's phosphate, nitrite/nitrate, and pH/alkalinity test kits. I've got nothing but good things to say about all of them. Each kit uses a 6 welled plastic plate to take the samples. You only need about 1mL for the sample, so if you test a lot, you are not emptying your tank. One thing I really like about these kits is the colour chart. The colour chart is made on a slide which gives a gradient to judge against, not just 4 or 5 colours. This gradient allows one to match colours more closely. These kits are slightly more pricey than some but most of them also give you at least 75 tests.
