What frequency does Z-Wave use?
Did you see significant improvement each time you added a coupler?The SA noise filters have not received UL approval yet, so therefore are not available for sale. When they receive UL approval, they will be very public.
UPB is a great technology, and I wouldn't consider ever removing it, but nobody should assume that it will work perfect with absolutely no debugging. In my house I had to use 3 bridges to get the signal up to an acceptable level. I've heard of another case where a PIM had to be used on both phases with a special joining cable to get the signal high enough. Its going to take some time to get all the bugs worked out, especially with the wide diversity of all the things you can plug into a powerline.
Post problems and solutions here, but also contact SA, PCS, or HAI and let them know your problems so they realize the problems.

interesting, my experience is exactly opposite. i was having a huge problem with my network and AO recommended putting in the pulsworx ppc-1's. i put them in and things got worse. as my system is based on ~100 sai upb devices, i called sai tech support. they were great. long story short--i now have two sai phase couplers and a sai pim. system now works.Just FYI using UPStart to determine signal/noise levels I tried several brands and configurations of couplers. I found that the inverting kind (SA if I recall correctly) actually made things worse in my case.

I think the difference comes from the distance between the transformer and your house.
