A not so thrifty way of avoiding spending your cash on an aftermarket 
heat sink is to spend it on a KXPA100.

Yes, I know you don't need that sort of power for digital modes, but it 
does eliminate the need for a bigger heat sink on the KX3 and it 
upgrades the KX3 in case you want to run power on SSB or drive a larger 
amp to get heard in DX pileups.
