E3D announced a more affordable option for an all-metal hot-end the Lite6, it’s compatible with the v6 nozzles and accessories such as the Volcano, but is half the price.

It’s limited to 240C because of the PTFE liner but for anyone wanting a better hot-end for their 3D printer this is a great upgrade.
I hope to get one on the Mendel90 we are building for 3D fab.
