Either the Auberins PID you linked or THIS ONE
will work very well for you. Both have temperature control and manual control. The manual control allows you to set the % of power delivered to your boil kettle. The one I linked also uses fuzzy logic which allows you to control the HLT water temperature a little more precisely.
The Love controller controls temp only.
I guess it all boils down to what your intended use is. Electric brewing, refrigeration control, or - ???
