The one my TV is on is a Hammond 169G, about $80 and good for 500W. I wired it up myself, it also has several taps for adjusting the line voltage if you want. A more convenient one for you may be their 171 series, as these come with 3 prong outlet and cord pre-attached, about $105 for a 500W one. Since it is pre-made, you might be able to return it if you aren't satisfied, as compared to one you have to solder up to try. If you have not tried putting some of your audio gear on iso or balanced power trannies, you are in for a surprise, so I doubt you'll not want to keep it, especially great with digital components. Anyway, if you get one, make sure its VA rating is higher than your TV power consumption. My RPTV is said to require up to 230W (VA), but a 500VA iso trannie is only a few $$ more than a 300VA one, and not much larger in size.

[Before, when I said that the filter doesn't help in the noise reduction, it probably actually is doing something. I just couldn't obviously hear it in my quick tests. The iso trannie removed all audible electrical noise i.e. none audible in audio system with volume at max. The filter would have a more subtle effect at much higher frequencies of noise.]
