Note the Manker E02 and E03 are 25% off right now, from the links on your list.

You might add the D25 series headlamps. I think they are made by Boruit, though sold by Sofirn and others. They work and are ridiculously cheap, starting at $17 here: https://www.sofirnlight.com/collections/headlamps

Added: they have a 20% off code too! So they start under $14 w/o battery.
