I have one, and it works great to eliminate manmade noise.  In fact, the 
result can be stunning.  I often have s9+10 hash noise on 40 meters that 
makes 40 unusable for me.  The ANC-4 reduces it below atmospheric 
levels.  I have the same noise on 80 Meters (at s9+30), and it does *not* 
eliminate it; however, I think that's because I don't have enough noise 
signal just using the whip (in other words, I need an external antenna on 
that band... or else, it really is just too strong)

The provided whip is plenty for all bands 40 and above.  On higher bands, I 
lower it to minimum height (about 8 inches).  Tuning is very easy (I've 
heard people complain about touchy tuning and the need to go back and forth 
between gain and phase control, but I've not found that to be the case)

I use a 12 Volt external gel cell to power it - that may help to keep 
power-line induced noise from getting to the balance circuitry.

One negative aspect for CW ops - you'll lose you're wonderful TenTec 
QSK.  I'm willing to live with that when it's a choice between listening to 
noise and having a QSO HI.
