New Heater

i am looking for a new heater for my 90l tank, keeping the old one as a back up.
what i want is something that is preferably black to blend in with my black background with a digital display.
i would like it to be easily adjustable without removal from the tank.
i am wary of the fluval e series as i have read some poor reviews, the aquael neoheater looks appealing though i am open to other suggestions.
