Hi, Scott --

     The short answer is that I just finished a 3-part series on rotators in
my Up The Tower column in CQ Contest magazine.  An SASE to TOWER TECH, Box
572, Woodinville, WA, 98072, will get you a free reprint.

    The slightly longer answer is that you can make part of your decision by
looking at the specs of the rotators.  They are

Type                      Rotating torque in/lbs         Braking torque
Hy-Gain CD45                 600                                       800
Yaesu G-800                   950                                      3450
Create RC5-1                   500                                      6000
Yaesu G-450XL                478                                      2600

    The other parts of the decision IMO are reliability, parts and service
availability and features.  I mentioned the Create because it has good
reliability and some interesting features.    You also get what you pay for.
