MG/Pre-Fert Soil Users: I gotta ?

I was at Lowes the other day and i seen a few different ones for around 5-15 bucks and some of them have a switch that goes between moisture, ph, and i think temp. The only thing im unsure of is how accurate they are as i have never used one. You could prolly look on their website.

I seen those at Lowes. They show: moisture - ph- and a light meter.
Flip the switch for different functions. I don't know how accurate they are?...but it's better than nothing...IMO. The light meter would help CFL growers measure the intensity of their lights, by comparing it to outside sunlight.
