Good power conditioner for non dedicated line

Im puting together a nice little system to use in my workshop and there is no dedicated line possible here in fact it would be sharing with things like a table saw. I am wondering if there is a power conditioner that is more suited to this type of application. I've had quite a few conditioners over the years and they mostly all seemed to improve the sound to some degree. I don't want to spend over 1000 on this.
