Not him, but... Microsoft nailed it with the Sculpt ergonomic keyboard imho. Detached numpad so you can put the mouse closer to the keyboard, gentle sloping, nice key travel. It's a good split starter keyboard. This one is cheaper than the combo version because it doesn't include the mouse. Don't get the grey bluetooth one. It has a numpad and weird feel along with bt issues. https://www.amazon.com/Microsoft-Ergonomic-Keyboard-Business...

It's a kinesis freestyle 2. It doesn't have slick trendy features aside from being split, and I am not madly in love with it. Instead I would say as it's mostly invisible to me, which is exactly what I want out of a keyboard. So, I would recommend it.

I also have a Microsoft 4000 at home for light/occasional usage and it's struck the point of being good enough for that purpose, and it was quite inexpensive.

(If your wrists are straight on a regular keyboard and your shoulders are not scrunched you probably don't need a split board)
