For Ender printers, Micro-Swiss have a pretty good name for all-metal hotends - and this is their “direct-drive” extruder kits. Not cheap, but if you are into 3D printing…
With the AUD reasonably strong and 30% off it comes in about $113 delivered. Your delivery charge might vary depending on location.
I’d like to support local sellers, but their price is northwards of $A179.
