What devices have you found useful when inspecting your stylii for cleanliness?

@goofyfoot My Zeiss D40 loupe arrived from China.  I thought the package was empty, because the loupe is so small and light!  Might have to buy a bigger loupe in case I mislay the Zeis and need to find it!

It would have to be the highest dollars-per-gram lens purchase I have ever made, but it is seriously good, especially when used as directed in a 30-mm gap between the eye and the object.  Works almost as well when it is close to the object and the eye is almost at infinity.

I see you also have big Quad electrostatics!

Yeah, there's not much to those lupes and they're costly. I use a pair of binoculars on my field camera. It turns everything right side up, which I prefer, so I've never owned a high quality lupe like the Zeiss. 

I have the Quad 2905's but with the 2912 panels, so I just tell people I have the 2912's. They're great with my ASR Emitter 2 Exclusive amp. I got lucky when I paired those two together.

I have a handheld 60x scope with an integrated LED lamp. I think I paid about $12-15 for it on Amazon and recently had to replace the little cell batteries, but it does the job just fine.
