I've had my best luck catching Ed early evening, his time. Be advised though that he lags way, way behind in updating his list on the web site. Anything out of the ordinary and it might already be sold. Case in point, his site still lists 4 top drawer JDJ's I bought from him early last summer, and these were from a private collection so am pretty sure he doesn't have more of them.
FWIW,
