	Many have been using Ohmite OY series ceramic composition 
resistors.  K0HA first made a post about these in January 1999.  Now 
Array Solutions, DX Engineering and possibly others are using them 
because of their high surge capacity.  I've had many 2W carbon comp 
resistors disintegrate due to induced lightning surges but I've never 
had that happen with the OY series.

Array Solutions now offers a 10W version made by a combination of OY resistors.

Newark has the 2W OY series available for $1.15 each.  The 470 ohm 
version is shown below:
