What is a good reliable heater?

[trilinearmipmap]

I have always relied on Ebo-Jagrs with good results in my FW tanks.

Lately on the discus boards there were many concerns about these heaters failing. The same sorts of concerns have shown up on the reef boards too.

Two of my 3 Ebo's (less than 1 year old, one is 2 months old) are not holding their set temperature. One "80 degree" tank is 75 degrees, the other "78 degree" tank is 71 degrees.

I have heard about the Won titanium heaters, I just want to know a good reliable brand of heater I can count on. A heater is the kind of thing you don't want to waste time thinking about, just set it and forget it.
