I have a large house (4500sq ft)with many x10 controllers of all flavors. I have an amplifier,coupler,filter,and 2 RF receivers, all driven by a CP290(never had any luck with CM15A? or CM11A? overheated and didn't work a few years back) and third party software. Would like to start moving over to 2way controllers. I have a PowerLinc USB 2414U, need 2 way software for my Vista computer that will download to the interface for free or cheap. Please make a suggestion. Thank you. Len
