There is indeed a 60Hz out picdiv from Tom Van Baak - http://www.leapsecond.com/pic/picdiv.htm. It's not in that list but ask Tom.
I've just used one (modified for 50Hz out) to drive a 1A H-bridge circuit that supplies a 12V peak-peak square wave to an old LED clock, replacing the original wall-wart. It works very nicely, and is driven by the 10MHz output of a cheap surplus GPSDO.
