Our local utilities don't use our meters, so I have no contacts to try to locate retired hardware. Plus as a developer I have very limited contact with users. Any time I go on-site with somebody they send along a salesman to keep me from sticking my foot in my mouth and promising too much.
I've played with Alphas and kV2 meters but our stuff tends to be higher end, used in transmission & distribution. (Big substations & plants, all transformer rated.) The thought of building a 200 amp meter makes our hardware guys break out in a cold sweat.
