I don't think you can go wrong buying a name brand Hanna or Bluelab or whatever running $50-80. I personally bought one of those $12 guys on eBay and its been working fine for me for several months. The accuracy seems to be fine at least against a 7ph solution and my 7 ph RO water. You have to be careful with them, they aren't fully waterproof, not that all the expensive ones are. I shorted mine out when I first got it by accidentally dropping it in my rez. It started working again like a week later after it completely dried out luckily.
