I had similar thoughts to try the quietline products, as my house has not-so-good wiring. I didn't want to spend 250 bucks on them and local dealers didn't have them for me to try.
I found the music direct has them individually for 27.50 each so, you can try 2 or 3 and see if you like them. (am in no way associated with music direct). shipping is cheap, and fast. Some indiana-based company has them advertised in stereophile for 24.99 each. can't remember the name though.
I thought they improved the picture on my tv a bit. a little less "snow" on cable.
Hope this helps.
