I just bought this one of off Amazon and I'm not sure if I could have found a better one for the price, but it' all I can afford right now. Of course, I said the same thing when I bought those $10 - 15 dollar ones .... what a waste of money when I could have used the same amount I spent to buy a decent one.

Hanna Instruments HI99104 Educational pH Tester, 0.00 to 14.00 pH Measuring Range, +/-0.2 pH Accuracy, 0.01 pH Resolution

Sold by: Amazon.com LLC
$36.00

I started a thread looking for advice on a reasonably priced ph pen, but didn't get any response. I already have a Control Wizard, but i needed something for mixing nutes. Good luck with your grow!

I use pH strips, because I am lazy and don't want calibratre pH pen everyday. It gets job done.
 
I have a couple of those amazon meters,Work ok if taken care of and more accurate then strips

That's true.
But you can buy pH strips which has range 5,5-7,5 which are better than pH 1-14. But not as accuare as pH pen, of course (if you handle them proper way).
