I like the titanium heaters, most brands are fine. as for watts, get 2 300w, one in the sump, and one in the DT in case of failure, keep the one in the DT set a degree or 2 under the one in the sump. This is what I do anyway, I'm sure you will get more feedback.

+1 on multiple heaters but I think you can keep them all in the sump, and I think 600 watts is about right.

And do 2-3 heaters instead of one big heater. It will distribute the heat and when one goes wacky and sticks on then you won't have a tank fry out from heat.

I would do 2 300w also that should be enough to keep tank heated even when it is cold.
