Wanted to follow up -- I ordered an IR543AH from homeautomationnet.com, split the units that don't have remote control onto a separate surge protector, and plugged it into the wall through an X10 appliance module. I then plugged the IR543AH into the unswitched pass-through outlet on the module (figure I'll get the best possible signal when it's plugged directly into the module).

With the ccf's that were included in the package, I had it up and running perfectly in minutes. And the bonus is that I can now control my other x10 stuff too.

Thanks again!
