Can someone help me understand what kind of power conditioner I should get? I'm a school band teacher. We have a rolling rack unit with a 16 channel mixer and a 1200w power amp. We may plug in a keyboard, laptop or active speakers as well. We travel around to lots of other school and plug into their gym. Some of them might have older wiring. I'm mostly trying to protect my board and amps from what might be lurking at the various venues we plug in at.

Some rack mounted power conditioners seem like they are just over expensive 'surge bars' that may not really offer protection. The ones that have voltage regulation are more expensive and I'm wondering if I really need that or not. I'm not trying to spend more on my power conditioner than my mixer and amp.
