Here we are railing against $500 mechanical keyboards, and some dude whips out $500 CW keys. The ultimate one-up.

The comparison with mechanical keyboards is spot on! Despite having nothing to do with radio or morse in any way, I was given a Vibroplex and it is quite a piece of kit - solid as a rock and obviously a tool well suited to its one task. It reminds me of some of the old tonearms used on turntables, with many springs, counterweights and possible adjustments.
