I've always been a big fan of Ebo Jaeger heaters... I used them for many years, until I got into saltwater actually and they had came out with the Stealth heaters. I like the stealth heaters, they maintain temp, auto shutoff when pulled from the water, and its black so it blends into my black background. They only thing I dont like is that they do not have a function light, so I dont know when its actually running or not for that matter.
