HEATER FAILED AGIAN! Any brand/style recommendations?

[mildcustom2]

I am using a single aqua medic 500w titanium heater and external aqua medic electronic controller in my 210. Complete package cost me 115.00$ The heater is in my sump and very consistant. The nice thing is that by having a seperate external controller is that the only way its going to fail is if I break it. The only good heater in my opinion is one that is electronic or solid state (same thing) if it dosn't say any of the later on the package its probably a cheap mechanical bi metal thermostat wich can fuse the contacts together leaving the heater on.
