You lot are all fairly lucky that you can even get a response from your regulator.
Here in Australia our wonderful regulator ACMA (Australian Communications & Media Authority) does 3/5's of bugger all with almost everything to do with Amateur Radio, except for holding out their greedy little hands for the $64.00 a year that we have to pay in licence fees.
I've had a complaint in with them now for almost 2 years about my various neighbours plasma TV's that has STILL not been actioned.
The interference was so bad here that it used to cream the front of my FT847 big time, at least now that I have the K3 it is 'bareable' but for the most part nowadays it isnt a problem, most of the people have upgraded to LCD's with the exception of one couple, who are empty nesters and are rarely home to watch TV nowadays. (Thank god!) :)

You guys in the States are lucky, the FCC listens and takes action.
In the UK our "Regulator" Ofcom blames radio amateurs for having
sensitive receivers, and as a consequence says it can do nothing to help...
