The PLC Thingee FX2 XOe works VERY well and IS an improvement over the original. I recommend it to you over other brands in that price range and many costing much more then $500. Don't let it's rough look fool you it is capable of doing a good job of filter out noise from your AC line and improving the color in your flat screen.
