Power Conditioner for Video under $500?

IME, Richard Gray does it better than anyone else.
I have been using a pro 400 for 10 years now.

["this is a very unwise suggestion as it would completely unbalance your transformer's loading as well as increase IR voltage drop of the phase bearing the entire load burden. Never ever do this.']

Once I described my goal to my electrician he suggested isolating my audio/video supply by doing what is described above. Along with an overall amperage supply increase for a shop and pool another panel was installed as well as a dedicated sub panel for the A/V. All the work surpassed local code, was inspected and certified.

It's very possible my electricians explanation to me was in layman's terms. Regardless the results were substantial and the cost for the A/V portion were very reasonable.

Sakahara, why did you get rid of the Haley? You seemed very happy with it. Just curious.
