Thanks, I didn't know they carried these. Unfortunately such test points
are comparatively large, for 0.040" holes and similar.

Come on Joerg. They're only three for ten bucks. You can afford them!

<yikes!> BTW, we use something similar for less than $.10 each. ...and those

I didn't say I can't afford them :-)

They are just a bit large for modern SMT layouts. Technologically a bit
