If you want a tester that's versatile while still being easy to understand, then the Rapitest 1880 is a good all-around choice. It has 3 prongs and a simple interface, making it user-friendly. One issue: the dial is situated so that you have to bend upside down to read it.
This Kelway pHD is a very pared-down instrument, making it easy to know exactly what you're looking at. It's ready to go right out of the box, with no batteries, chemicals, or anything else needed. It only measures pH levels, though, so you may need to buy other tools.
The Luster Leaf 1601 isn't a meter, but is actually a testing kit. It has a patented Color Comparator system that makes it easy to see exactly what's going on with your dirt -- and what do about it. Unfortunately, some users say it gives inconsistent results.
Getting the right pH levels is one of the most important -- and trickiest -- parts of having healthy lawns, which is why the XLUX T20B is worth every penny. It also measures moisture levels, but the accurate pH values are what make this device such a home run.
