They're not really cheap... The only surge protectors/power conditioners I'm really familiar with are rack units which are quite expensive, such as Furman or other similar brands. Quite frankly, I really wouldn't bother. Unless you're running a multi-thousand dollar rack-based rig, it's really not worth looking into much.
