Sandy,
It depends on the damage. If just one FET or two are bad, the cost to replace probably justifies the repair. Common thinking is that anything beyond a simple FET failure has likely stressed other components to the point of being unreliable in the future.
I have had success with larger Weller tips using Mike Betts' method. However, I heat only the pin and remove it when the solder melts. Then I clean the hole using solder sucker rather than the wick. If one of the holes is still clogged, then I simply heat the new transistor pin as I insert it.
