The Leviton HCM06-1TW are X10 2-way and use the wired slave switch. They're a bit expensive and (I believe) out of production.

I've had a number of the receive only HCM06-1DW installed for ~ 9 years now. They've been bulletproof. They have the gated AGC for contending with line noise and I've had no false switching as compared with other X10 products.
The Leviton units do incorporate the resume dim feature and they will not activate in response to a dim or bright command. They are best operated using the X10 extended code protocol. Not sure if your controller supports this. They also support X10 extended code "group" or "scene" programming which I've been using for coordinating on/off sequences.
I've been moving toward Insteon over the past few years. The HCM06 are the last X10 remaining. I can't bring myself to replace something that has performed so well for so long.
The above said, this product line is nearing (or at) it's sunset. If you are simply replacing existing units to "get by", they may be an option. If you are looking for a product for the long haul, it might be good to look at current technology.

One last item - I do not know if the 2-way version will broadcast a on/off status when the slave unit is activated. My guess would be yes, but I have no way to verify.
