I am in need of a decent 50 or 100 watt dummy load to properly align the
transmitters at full power.

Gregg-

Take a look at http://www.mfjenterprises.com/produc...rodid=MFJ-260C for a
dummy load that will withstand 300 watts for 30 seconds, or 25 watts
continuosly.

It costs about twice what you mentioned, but is less than similar Bird models.
If price is important, search E-Bay for dummy (load,antenna).
