Best bang for buck powercond. ?

I've had great results with my Blue Circle Music Ring. It's a balanced conditioner with seperate digital and analog outlets. They're in your budget new and also show up occasionally used, here on the 'gon.

I live in a big city in a big Apartment building and clean power is not to be found. I use a big Powervar (model 1100-12?)46lbs and plug in my pre-amp, transport, dac and ultrajitterbug. Works great and only cost me $100+S&H on Ebay. Now that they are becoming known to audiophiles the price can be double but is still a bargain. I plug my threshold amp directly to a cryo'd outlet from Locust design group and it took some of the grain out of the top end. Smooth and a tweek that is mentioned because I might try to upgrade (change) the powervar outlets to these outlets.

HOw about the Audience PowerChord. Great bang for very little bucks. I use them on my amps and Audio Aero CD player. They are sensibly priced.
