One possibility is to get an FNET/GridEye unit of the University of Tennessee's monitoring stations.
Operated by the Power Information Technology Laboratory <http://powerit.utk.edu> at the University of Tennessee <http://www.utk.edu>, FNET/GridEye is a low-cost, quickly deployable GPS-synchronized wide-area frequency measurement network. High dynamic accuracy Frequency Disturbance Recorders (FDRs) are used to measure the frequency, phase angle, and voltage of the power system at ordinary 120 V outlets. The measurement data are continuously transmitted via the Internet to the FNET/GridEye servers hosted at the University of Tennessee and Virginia Tech <http://www.vt.edu>. I have Unit 853 of the Western Interconnection in the tabular display in their web site (http://fnetpublic.utk.edu/tabledisplay.html). The unit, about the size of a book, connects to the Internet via a cable to my router and has a power line connection and a small GPS antenna. The LCD display shows voltage and frequency; unfortunately there's no way to record this information on site (at home or wherever).
