Summit was selling red ones for a while. Junky but easy to find at the time.
Taylor vertex had a dark maroon cap made of good heavy material, ribs between the terminals, and a vent.
I don't know who made it for them but they say they can't get it any more.
They now sell a lighter one, no ribs, under the same part number. (and for the same high price as the heavy one) :(
