Power Conditioner for Video under $500?

IMO spend the money on having a couple runs of metal clad 10 gage wire with isolated ground receptacles, metal termination boxes, and dedicated 20 amp breakers. Have the electrician move the motor driven appliances and lighting breakers on the other leg of the breaker box. Putting two receptacles on each run will give you eight outlets to plug into. There's your power strip

It's so common for people to spend thousands on power conditioning without first spending $200-$400 for proper AC wiring. It can be one of the most noticeable and least expensive tweaks going.

["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.
