HHKB Lite domes are not regular domes. They are hardened domes, to hate you for not buying the Pro version.
The HHKB Pro is good enough. It certainly doesn't feel like $200' worth and it doesn't smooth the floor hit when you bottom out, but it's solid (as is the lite). But I found it impossible not to bottom out, because the initial resistance of the keys, being a rubberdome, is too high to be absorbed by the remaining (spring) resistance. You hit the bottom just the same moment you overcome the initial rubberdome resistance. It makes you type faster, but so do island-style keyboards.
