Not the same ol' key...

[admin]

Straight key, twin paddle, and yest, maybe 'bug' (Vibroplex) all look pretty much as you would expect; they haven't changed much for years.
Maybe because they're perfect???? Maybe because you haven't seen some new designs, as yet not common in US:

This lot were culled from a page on https://aliepress.com with search criteria "morse key". Not a recommendation for or against, as I haven't used any of these. Most seem to sell for $40 - 50 with free shipping.

FWIW, I use a "K4" heavy chromed brass straight key also from https://aliepress.com, currently about $40. Personal mods were some soft feet, a 1/4" plug and lessening the spring tension for a lighter range of touch.

Odd, but there seemed to be no 'bug' in this collection.
