All ph probes created equal?

I'm sure some people have some opinions about this. What is the longest lasting, most accurate ph probe available at a reasonable price (around $50)? Or are they all (milwaukee, pinpoint, neptune, reef fanatic) about the same?

At that price range, I get Pin Point. Neptune are also good

Milwaukee probes are epoxy encapsulated at the top, meaning that they can be fully submersed, whereas Pinpoint cannot.

Early on, I had to replace 2 Pinpoint probes that died when the suction cups came loose and the probes unded up at tthe bottom of my sump for an undetermined amount of time. I switched to Milwaukee, because the Pinpoint probes were not covered under warranty, due to being fully submersd.

Hmm, I run both a PP and Neptune PH probe submersed all the time and both work well.

and what are the differences between the standard and lab grade probe, is the lab grade last longer and more accurate, are pH probe interchangeable, meaning can I use pinpoint or neptune probe on my Milwalkee controller.

I heard that there are some serious Lab grade probes that you can buy. These are refillable probes that have a very high price tag. I have no more info but possibly some one else could point you to a website that has them.
