My experience with spudgers or probes is similar to Al's.
I thought "get the best" so I imported some Bergeon probe sticks.
Like Al, I quickly found them to be crap. The tips were quite frangible and tended to bend and split quite easily, sometimes leaving small bits of plastic on the work.
I also tried some that were used for mobile phone repairs (the blue ones). They were better than the Bergeon, but the tips tended to bend if made too fine.
I ended up finding a local supply of excellent probes, well, actually acrylic knitting needles from the local craft shop (green and yellow ones below).
They were cut down to size and the tips sanded and then polished, either to blunt points or chisel edges.
They perform very well, and as you can see by the green one, even when bent from pressure the material doesn't chip or fracture, it just bends slightly so it's easy to re-finish the tip.
Best of all, they are available locally, cost way less than "special watchmaker's tools" and you get four probes from one pair of knitting needles.
Here is a view of the tips, showing the Bergeon ones I now no longer use.
