There are still plenty of those available on Ebay:

The type of SPX EVSE the OP has requires cable upgrade when pilot is to 30A. So the question that has not been answered yet is what was the pilot setting in the EVSE?
Another option would be EL-50600-A used to be SPX, now it has BOSCH written all over it http://www.pluginnow.com/power-xpress" onclick="window.open(this.href);return false;. It can be adjusted to 24A to work with 30A dryer outlet.
