I like both the Jagers (used to be Ebo, now made by Eheim) and Stealths. The only downside to the Stealths is they don't have an indicator light, but they are virtually unbreakable
Stealths are the way to go as long as you can deal with it not having an indicator light. I bought an Eheim Jager a while back and was fairly displeased with trying to get it adjusted from the beginning. Once you figure out it's secret trick to make it work right it maintains temperature very well though.
I agree, I love my stealth's, used jagers and don't like the fact that they aren't submersible. Also, had other heaters crap out a lot before I got the stealth's, haven't had any problems yet, 2+ years so far.
