I bought an Apex from a guy who never made it all the way through setting it up. He made an attempt to store the probes properly, but its my understanding that they need to be replaced every so often anyway and I'm pretty sure they have long passed that time. I'm looking to buy some new probes and I'm wondering - do I really need to care about ORP to the point of buying a new probe? Thinking about simply skipping this one.

Short answer is no. For most people, ORP is not used. It can be helpful in understanding an aquatic system’s health, if you research it enough to understand what it is telling you. In short, ORP is a measure of the availability of electrons, which are used to drive biological/chemical reactions in the system.
Fwiw-
You can use the 2nd (ORP) probe port for a pH probe, if you like.
For example: if you are running a calcium reactor, you could put a probe in the reactor’s chamber to help monitor the pH & control CO2 flow, if you wanted to.

I prefer the Pinpoint pH probe, also double junction.
I wouldn’t sweat the salinity probe right now. They are very finicky to set up, calibrate and keep accurate/stable.

If and when you get a neptune salinity probe, get the kit to stabilize it- add on kit online and you can get more stable readings- otherwise suggest don’t bother getting salt probe as it is super finicky and problematic.
Here is the kit that sharis100 was probably posting about above. I have heard good things with this kit keeping levels stable because it keeps the micro bubbles away from probe tip. https://www.saltwateraquarium.com/salinity-probe-stability-kit-sps-without-pump-vca/

Agree, skip the salinity probe for now. Too finicky to be much use unless the stability kit helps it out.
The ORP probe is probably still good. They do not dry up like pH probes. Clean it in some vinegar and gently scrub with a toothbrush. Calibrating is not maditory, you are watching for sudden drops which could indicate a problem.
Best pH probe I have found is the BRS double junction. Pinpoint is good too. I steer clear of the Neptune pH probes.

Why does BRS recommend this? When it comes to probes not all are built alike. We went through many different brands of probes to bring one in that we were comfortable putting our name on. With high-quality materials, the BRS Lab Grade pH probes will last longer than most other standard grade...

Milwaukee states 12-18 months. Others have 18-24. Polls from other Reef sites are all over the place, with most stating somewhere around these numbers. Outliers go up to almost 10 years! I’m not sure I would trust one that old.
