Anyone know of a cheap dimmer or some other rheostat(potentiometer) than is rated to handle a blower motor? I see all kinds of light dimmers on amazon and I would preferably buy from amazon. But I know a light dimmer probably would not hold up to long if at all. But with the soon to be nc-30 sitting halfway inside of my fireplace I would like a simple plug in variable speed control to operate the blower. If anyone knows of a trusted preferably under 20$ unit let me know please
