Elecraft has been great about getting knob replacements out very quickly.  I 
first noticed a crack in my knobs after using the K3 in ~ 40 degree 
temperatures.   Going forward, knobs with a brass collar would be a good 
choice.  Contesters and those who take their K3s out on DXpeditions may want 
to consider keeping a spare set available in the event the knobs crack in 
the heat of the moment.
