Milwaukee and American marine pinpoint PH are the 2 standard meters in the hobby. They both are very nice. The pin point reads out 2 decimal places and the milwaukee one.
I got a milwaukee for about $65, I think--it does read out to 2 decimal places. I still don't feel very comfortable about my pH readings, though, as they are always, always low on the meter and fine on drop kits. So I don't know which is wrong!
