I made one, but it was suggested by someone else.
Still use it, works great, smallest drills i have are 0.5mm and those work
just fine.
Breakage only due to accident (pushing somehing sideways against the drill
etc.).
I have no problems now to noticeably dull drills with this machine, so i
get quite some life out of them ;-)
Use a proxxon though no dremel.
I agree with you that a useful CNC could be built far cheaper than was
suggested, at some point when i have more time and space i'll build mine.
