Are you running the Manager Essentials or with the added features of Manager Plus?
Since Smarthome has labeled the 1132CU and Manager Software as Legacy and has not even corrected for the new Daylight Saving Times.
We did a workaround for the Daylight Saving thing. The software is also listed as not working with Vista and I would guess Widows 7 also. Again called Legacy.
I use to use a 1132CU myself and it still is doing power line monitoring when I do my X10 experiments.
I would say not to replace the 1132CU with a replacement 1132CU.
Smarthome really doesn't have an X10 controller any more. Just some Insteon controllers that at present also can support X10 in most functions.
The 1132CU is still on the sales page.
Maybe the X10 AHP setup with the CM15A controller not the lower cost AHP with CM19A Interface. May do what you want to do.
Are your modules X10 models or Smarthome X10 modules? The X10 and Smarthome modules handle dim commands differently and that is why I am asking.
As for your bad reception areas. That is more like signal problems. Like signal suckers and noise makers. That probably would not change between the 1132CU and the CM15A. We have many troubleshooting threads on such things.
