Cobalt Aquatics neo-therm. I have three and love them. They're pricey. I know you aren't local and that's too bad. There are at least two sponsors that have them for less than online. $20 less for the 200 watt.
I like the Ebos too but they are BIG. The Cobalts are fairly new but if they are as good as the reviews say they are, they are a good choice for smaller tanks. They're plastic too, with a clear digital display.
