One good part about Topre is that they already come with Dyesub PBT, so you won't have to buy a decent set of keycaps from somewhere. I haven't tried Topre, so I can't comment on the price (Which has thus far prevented me from buying it. If only I could try it first... (even the switch try bags are too expensive for me!) )
Another good part is that they should be relatively easy to sell to the healthy Topre following that exists here, and elsewhere, should you not like it.
