What heater are you using?

Thanks for all the input so far. I'm truly surprised not more people are running titanium heaters! When I had 2 Jager's crap out on me and stick on I bought what I could find locally and got 3 - 300W Aqua Heat Titanium heaters from a hydroponics/plant place. They have an external temp sensor and controller and I've been pleasantly surprised by their performance. Their actual calibration is a bit off (difference between actual water temp and the numbers on the dial), but I have a stand alone digital thermometer that I use to set their temp and it's worked really well.
I was hoping to get more feed back on Finnex and Blue line. I thought they were supposed to be decent heaters but so far only one person on here is running the Finnex. Hmmmm...
I like the idea of running several heaters that no one heater can cook the tank if it fails.
