Maybe consider dropping the dual voltage requirement. The advantage of using the OpenEVSE instead of the stock unit on 120v is negligible.
After a cooked relay (my fault) I just switched over to an inexpensive definite purpose contactor like the one Chris sells and in the process gave up dual voltage, but in two years I've never used my OpenEVSE on 120 so it was no loss. The simplicity and the robustness of the contactor makes me feel better about the whole system now. The removal of the fuses and crimped connections got rid of multiple potential failure points (including my less than perfect crimps).
Whatever you chose, be sure to let us know and share some pics.
