Appart from the hybrids, there are some good ones? Its a matter of taste, but I have an IBM KB-8926 made by lexmark and a Unisys E8HKB-5923 that feels good, no click though.
I've seen ones that in addition to the plastic cilinder or square that goes into the rubber dome, have a couple of plastic bars at the side that enhances the pseudo mechanical feel. And if they use a thick layer of plastic similar to the topre, they feel better.
I somewhat liked the new apple aluminum kbs for a while.
I don't know if the topre itself qualifies, but its good enough for me, behind from the cherry's MX
