Five Gallon Heater

[Varmint]

I have a five gallon tank I'd like to start up again, but if I do, I'd like to put a betta in it. So I need a heater.

What is the best brand to buy? My budget for a 5 Gal heater isn't much. 20 being max. I'd rather buy a heater for my big tank if I was gonna spend more.

I would get a tetra submersible heater. They don't need to be adjusted at all and they are quite reliable. $11.50 on Amazon right now. Of course any 25 watt heater will do, but that Tetra heater has been pretty good for me as it keeps the water at 78f, which is good for a betta.
