I am considering one from the 2 links under alternative in your last reply or this one below. I am wondering why the Ludtom and the one below say total ports is 4. Also, the Ludtom says it has "temperature control." I am wondering how much cooler this one is to justify the extra bucks. Of these 3, is one superior than the others?
