Research-backed, not algorithmically invented.

These are desk-researched listings, not factory audits or endorsements. Address, equipment and quality claims link back to their publisher. An unavailable capability or certification is unknown—not a negative finding. When online, the preview can match published official addresses against the U.S. Census public geocoder; these street-range estimates appear as green pins. Unmatched, ambiguous or unpublished addresses stay in clearly labeled city-center groups. Street-range interpolation is not a confirmed rooftop or entrance location. Contact each shop to confirm machine availability, quality scope, lead time and export-controlled work.
