1. Oil analysis - Oil is the lifeblood of the machine, and a good lubrication program will do the most to keep equipment from reaching the P-F curve in the first place. At $30-$35 per sample, it's easily affordable.
2. Ultrasound - It's super intuitive to use. The tool needs to be capable of detecting both airborne and structureborne noise. Finding and fixing compressed air leaks will easily pay for the tool and for a few other tools. Using it in contact mode for UE-assisted greasing will help optimize your lubrication program, and it will help identify bearing defects and any other mechanical problems that generate high-frequency vibrations. It can detect a huge range of anomalies.
3. Infrared - Again, super intuitive to use, and can detect a huge range of anomalies, like later-stage bearing defects, malfunctioning steam traps, shaft misalignment, electrical problems, internal hydraulic leaks, plugged heat exchangers... the possibilities are endless. Be sure to get one that allows you to manually control the on-screen temperature span, as this is essential for comparing across different equipment and for tuning out background heat signatures. (The FLIR E6 is my favorite entry-level camera.)
4. Vibration analysis - Powerful, more expensive than other tools, with a steeper learning curve. A key part of a mature condition monitoring program. (Contract or in-house manual routes and/or permanent wired or wireless sensors is a whole separate conversation.)

I agree with many of the comments above regarding vibration analysis, thermography, ultrasound, and oil analysis. All have delivered significant value in the operations I have been involved with.

However, one of the highest ROI activities is often going back to the fundamentals. Training operators and maintainers to use their senses-to listen, look, feel, and question abnormal conditions-can identify issues long before they become failures. A strong operator care and basic condition monitoring program is often the foundation of reliability.

Oil analysis has been particularly valuable in extending equipment life and identifying wear mechanisms before catastrophic failures occur. Combined with thermography and vibration analysis, it creates a strong predictive maintenance framework.

The real return, however, comes from developing people. Providing maintenance teams with opportunities to learn, coach others, and grow into reliability-focused roles creates a culture where defects are identified and addressed early. Technology is important, but engaged and capable people ultimately deliver the greatest long-term ROI.

I have to agree. I've seen where where the lube techs, even without the benefit of predictive technologies, have found more equipment defects than all of the PdM techs combined. They touch every piece of rotating equipment in the plant, and by simply paying attention they have noticed all kinds of problems.
