What would be an accurate and reliable thermometer for a 55 gal fresh water tank?

The most accurate one should be the digital thermometer...
However, in my opinion, the simplest mercury based
glass-tube thermometer is good enough. More important
item should be the heater, whether its temperature control
is precise or not makes a big difference...

The LCD stick on type are the most inaccurate in my opinion, I use an infrared temp sensor to check my tanks, and the ones with the LCD stick on types can be up to 8 degrees off.

I agree the heater is the most important.
