Ergo-S-1

For those with more time than money, you can build an open-source Advantage 360 clone for around $100 USD: - https://github.com/wizarddata/Ergo-S-1 I'm not the creator, but I do have a repo with a purchase list that shows what stuff to buy from AliExpress: - https://github.com/arcanemachine/Ergo-S-1-Extras It takes about 10 hours to put together. You'll also need some nerd tools: access to a 3D printer, soldering iron, etc.

I switched from a Kinesis Advantage 2 to a Glove80 over 1.5 years ago (not custom, I know) and I love it. I also made some Dactyl Manuforms, but their key wells are not as nice as the Advantage, let alone the Glove80. They also have pretty bad thumb clusters (though with Cosmos it's configurable), not a good palm rest, etc. The only custom board I would be interested in (if the Glove didn't happen) would be: https://github.com/wizarddata/Ergo-S-1 Since it also seems to have good palm rests, etc.
