50 watt heater in a 3 gallon Eclipse?

I'm moving my betta from his 1 gallon mini tank to a 3 gallon "monster" Eclipse. In order to keep the water temp up near 78-80, I'd like to get a heater. There's one for sale locally for $10, but it's 50 watts. Obviously it'll have no problem heating the tank to ridiculous temperatures, but will it work properly for a tank this small?

Also, is there an EASY way to feed through the filter access door? There's a tiny gap between the filter "rack" and the hood that I can almost fit my chubby digits through, but it doesn't seem to be as convenient as people make them out to be. It'd be nice if they had a top front door for feeding / water changes / viewing.

at walmart they have a little 7.5 watt heater for $7 its only about 4 inches long.

Does it have a way of adjusting the temperature?

I don't know about you, but a 4 degree fluctuation over 12 hours is good enough for me. I'll keep an eye out for further differences.

He looks good to me :)
