Here's another option I came across online.

Only $200, but still looks pretty well made. I'm still not convinced this or the Dinan are adequately weatherproofed at the connectors, but I may be overly concerned...
Shouldn't there be boots over the area where the wires enter the connector to seal out dirt and moisture? (like Bosch connectors) Or is the sealing built into the connector?
One observation, the installation on the one sold by ECS is a bit simpler. The Dinan requires tapping into 12vt+ and adding grounds. Where as the one sold by ECS appears to get all its power and grounds through the existing valve wiring. It also can be integrated with HomeLink like the Dinan.
