That was a long, long journey just to replace a set of a 60% keyboard. That is the issue with ALPS stems. You should be interested in an interest check for a full set of double shot keycaps for ALPS that is now at SP group buy site.
Oy. The stabilized caps (except the spacebar) won’t work on his V60 keyboard. It’s not clear that he has a keyboard that they would work on. If not, why should he be interested?
It wasn't too difficult to gather up some donor boards, and the stabilized caps from the Dell AT101W worked just fine on the V60. I am typing on it now, with all "new" caps (except for the spacebar), and the stabilized keys are working beautifully -- crisp and even response with not a trace of rattle.
If the stabilized keycaps in the set on the SP IC would not work on the V60, then I suppose I would not be interested. In addition, I would much prefer to have PBT, at least for the alphanumeric keys. On the other hand, for the sake of promoting Alps/Matias switches, I will take a look at the SP IC and possibly cast my vote.
Currently, I am using alpha keys from a Data General 6311. They look like dye-sub PBT, but they feel too smooth (although not clammy like ABS); I have not yet done a salt-water density test or acetone test. Although I am reasonably satisfied with the new face on the V60, I am going to continue looking for some dye-sub PBT caps that have a slight pumice-like texture. I have an AEK, but I don't particularly like the font, shape, or color of its keycaps.
