If you're talking light-duty, for modest-sized homemade antennas, there are several azimuth-only TV rotors and light-duty ham rotors that would do the job. Just mount your antennas at a fixed elevation of 15 degrees, and you will be able to work most passes up to 45 degrees or so. (If they go higher than that, just work 'em early or late in the pass when they are lower).
Look for a rotor that provides a DC position feedback voltage to the controller (0 to 5 volts for 0 to 360 degrees is what most satellite controllers expect - you may need to modify the rotor or its controller to provide the voltage.) There was one available at a lot of home-improvement and *-Mart stores a few years ago called the Orbit 360 that was ideal. Check eBay, Craigslist, and The Rotor Man on the web for that, and other options. Software-wise, I am a HUGE fan of SatPC32. The developer, Erich Eichmann, is a member of this group and provides unparalleled support, the price is very reasonable, and 100% of the proceeds go to AMSAT to build and launch satellites.
