Alternatives to official probes

[firechild]

I'm looking to replace the pH, ORP and EC probes on my Profilux. The GHL pH probe is AU$141. I know I can buy a pH probe for about $10 though obviously there is a tangible quality difference. I'm hoping there is a middle ground where decent quality probes can be found for less than what we pay for brand specific products. For anyone that has replaced their Neptune/GHL/Hydros probes with another, more affordable option, what are you using and do you feel that the results are similar to the originals?

Appreciated as always Gaël. I knew double junction was preferable but it's good to know the details.
Given that we don't have ultra precise measurement requirements, I think I'll go with a cheaper double junction probe. I have my doubts that a $220 apex branded probe is substantially better than a $55 probe.

I have used Pinpoint and Milwaukee pH probes on my Hydros. I use the all glass Milwaukee in my iV and it seems to work great in there.
