What is the BEST heater available!

[Whatigot]

this is a really simple heating solution I came up with for my tank...
I just have 2 50 watt heaters in my sump that are running on timers opposite from the halide lighting.
There is a visitherm 250W heater in the tank itself and it's on full time.
So the lights click off and the heat turns down at my house for the evening and the 2 50 watt heaters in my 20 gallon sump pop on and BAM......80.5 to 81 degress all day since I set this up 2 weeks ago.

things may change in the summer though, but just thought I'd share my cheap and easy heating method...
