I skipped the whole mechanical keyboard acquisition cycle (thanks to a comment or two from HN), bought a Niz, totally happy with it and best keyboard I've used, haven't been tempted to keep searching.
Could never find Cherry MX Blue/Browns which worked for me- always triggered RSI in my outer wrists. Chiclets caused problems in my fingertips from bottoming out.
Topres gave me a decade of heavy coding after battling RSI and I love them for that. But this Niz is making me smile. I'll get another Niz before I go back to my Realforce.
