Sorry for the delay, I didn't notice the replies. I'm not sure what else you want to know.... the $59.99 unit (10 outlet) is the model I have. It is about the size of a decent surround receiver: similare in size to all the midrange Denon, H/K, and Marantz units I have ever had. It's a bit bigger than my current JVC digital unit.
I'm not so sure if it does true power conditioning (feeding out a sine wave and all that) or if it is just EMI/RFI filtering. I could have swore I read that it has a proper sine wave inverter, but I can't find that info anymore.
Anyways, it also has telephone connections, and coaxial cable connections (for your cable or Dish or DirecTV signal). 2 of the outlets are "always on", the rest are controlled via the front power button. It has indicators on front telling you what the power level is (mine hovers between 115 and 120v).
It is a really solidly built unit, probably not quite on par with some of the Panamax/Furman/etc offerings.... but then again those are many times more expensive.
Here's a bad picture of mine in my old temporary setup, it's the best I have.
