I'm looking for a high-quality loupe that's maybe 15 to 20X

• Peak Optics 20X illuminated scale loupe
  • focusing mechanism
  • has reticles
  • seems kind of big for hiking purposes
  • $154
• Peak Optics 20X folding loupe
  • focusing mechanism
  • no lighting
  • no reticle
  • $67
• Peak Optics 25X and 50X pocket measuring microscope
  • has a reticle
  • has a lighting accessory, but that's currently unavailable from the manufacturer
  • has a focusing mechanism, though it's a bit weird
  • 25X is $95, and the 50X is $115
• TODO — add this
• TODO — add this
• also possibly consider:
  • Peak Optics pocket microscopes
