ok so first fuck you topre isnt 'just an expensive rubber dome'
each key has a spring that acts as a capacitor and uses a timing circuit to determine how far the key is pressed down making it not a switch at all
with topre you do not need to bottom out to actuate, unlike a membrane, and uses high quality domes to ensure that your typing experience doesn't suck
it's smoother than nearly any mechanical option and can be modified somewhat easily
with an easily upgraded spacebar, the keycaps are among the best available

if that's not worth $200, nothing is
