IMO, some of Kailh's clickbar switches are a better bet than Cherry's click jacket ones. They also tend to be cheaper!

Box Jade is relatively soft to press with a sharp tactile event, Box Whites are softer still, and Box Navies are too stiff for me. I currently use Pinks, since they have a medium-thickness clickbar.

And since someone might want linears (no bump or sound in the keypress), Gateron Yellow switches are a great value. Not the cream of the crop, but very nice for what they are, and you can buy them from any number of sites.
