Lee,
If you are willing to do a little construction, WA8SME has a very nice design which appeared in QST, called WRAPS. Completely shameless plug! You can order the key circuit board, bare, and programmed PIC chip on the AMSAT Store:

It is $30 plus modest shipping. You can find a link to a download of the article. I haven't built one myself, but construction is straight forward and doesn't require any exotic tools or skills.
Over the years there have been a few other similar controllers, but none that I am aware of which are currently available assembled. Another approach some have used is to use Yaesu rotators with an inverter to power them. That would not be a cost effective way new, but you sometimes find them very cheaply at hamfests.
73s,
Alan WA4SCA
