I'd recommend the Oakton brand, just about anything they have. You can pick up their Ultra Basic pH meter for around $70-80 online or in-person.

I personally wouldn't buy a combination (pH and EC) meter because they tend to have more problems, expire quicker, and require more frequent calibration to maintain accuracy.

I also would tell you that I will not buy anything from Hanna. They have awesome super-high end pieces, but anything you would want from them would be worthless (in my opinion).

Notice how every paragraph begins with an 'I'? They're all opinion, so don't take it to heart.
