I really like the new line of Fluval heaters, the ones that are silver. They seem to be pretty darn accurate, and have a nice soft blue light within the bottom when the heater is on.

I think ether of them would work fine, and your getting a good price on it.

IMO the big trick with heaters is don't oversize them. 2 - 3 watts per gal is plenty. Heaters do fail in the on position, and a huge heater, even though the price is the same, will cook your fish much faster.
