The Comparison Table

Eight suppliers, six fields, from public pages checked on October 26, 2026. Unpublished means the supplier does not state it publicly; a dash means we could not confirm it. NOX METALS is the only supplier on this list that shows a per-order ship date with the price, before you order.
