Thanks to bestalign for starting this poll! We've contacted the vendor on your behalf and they've made the Keycool 84 2S Mechanical Keyboard available.
For those voting for the Kinesis Advantage: be aware that they are currently developing a version using Cherry ML switches for the F row, replacing the current membrane buttons
The big problem with the Advantage is that you have zero chance of swapping out complete keysets, the enter and space thumb keys are titled vertically and the function keys cant be changed. I've been using these since they came out in '96 and they're awesome but I can't see many designers wanting to make something for what's a true edge case, more's the pity.
