Caddock resistors are great www.caddock.com and are very good at high 
frequencies.  The 100W ones come in TO-247 transistor type packages  and 
are a  resistance film fired onto a flat ceramic substrate. Digikey sell 
them.  Downside is the requirement for a heatsink.  Upside is GHz 
non-inductive performance.
