I like 62g ErgoClears, but I'm willing to give Topre another chance with a Novatouch and SA keycaps (when I win the lottery or something). I've read that combination is very nice. Probably go with spicebar's silencing mod and maybe 55g domes (and suddenly the price skyrockets even further).
They at least solve one of the biggest flaws of membrane rubber dome boards, the actuation point is not at bottom out, so you don't have to pound on them to make sure they actuate which is much better for your fingers wrists and hands long term health. And the feeling is somewhat different despite the characteristic S-shaped force curve all rubber domes have, partly due to the capacitive sensing spring.
Still a rubber dome, though, and way overpriced. They use a sheet of rubber and some springs instead of individually manufactured switches, they have simpler construction, etc. all of which makes them cheaper to manufacture than a board that has individual mechanical switches and yet they still charge you a massive premium. Great that Noppoo at least are starting to make some similar boards, so maybe we'll see the end of the monopoly, a little bit of healthy competition and lower prices... Maybe.
