Fish Tank Heater Needed

[Hurricane]

I am working on my elk skull for a Euro mount and I need a good fish tank heater. What would you recommend for a good heater? Thanks Robby.

It's going to be submerged, yes?  Depending on the volume of liquid to heat, just about any cheap-o will do if your acceptable temperature range is wide enough.  Don't trust the numbers on the setting dial - get a separate tank thermometer.
