PH Tester Recommendation

Hi, can anyone recommend a digital PH tester? I want to use this for mary, as well as an outdoor garden. I tried one of those cheapo ones ($8.00 at my grow store), but that was as useless as using a pencil. The needle was ALWAYS on 7 no matter what it was in. I even stuck it in a lemon and it still read 7.0!

check out Blue Labs, I have the combo meter and it is well worth it!!!!!

Look on e-bay and get a feel for what is available.I bought a TDS-3 for around $20.00 and have had no trouble with it.I have had it three years now and use it a couple times a week.I also picked up a ph meter for around $20.00,they are easier than the strips.
I would not buy a combo meter,if one function fails you will end up purchasing another one anyway.OPH
