I've had Ebo-jagers in the past and have been happy with them. You might consider two 100-watt heaters, instead of one 200 watt unit, so you have a fall-back if one conks out.
I am running a Via Aqua Titanium heater and I really like it, I have read that the Finnex Titanium's are very good. I will be switching over to all titanium's soon. The stealth by Visa Therm also seem to be very good
