i saw that deal for monster ones also,i just cant buy anything monster after all the crap they have been giving any little company with monster in its name.so i bought the pureav pf40(170shipped)
the digital readout is screwed up(shipping it back this week) but other than that i can say i like it-
appears to have helped my hdtv wih the red bleed it had durring live sports on cbs(only cbs

)
my cdp also appears to like it as does my tuna-
i am running 2 odyssey extreme monos,tempest pre,hdtv,tuna and cdp so far-not hooking everything up because its going back because of the display for a replacement-
i have noticed zero bad effects added to my system with it installed and percieve a few good ones
