Recommendation for submersible heater.

My heater just gave up the ghost (fortunately, I have a relatively  
stable apartment temperature), so I'm in the market for a new heater.  
I'm trying to decide between the Ebo Jager submersible and the  
Visi-Therm. Has anyone had any experiences (good or bad) with either  
(or both) of these heaters? Thanks in advance.
