Your only choice for inline heaters are the hydor's. I've been using mine for a while now, bought it used, so I don't know how old it is. It works like a champ.
I think what a lot of people don't realize is that the heater is the single thing in our setups with the greatest chance for causing carnage. Barring a leaking hose fish will be able to live in unfiltered water until you get home from work. But a stuck on heater will cook them in no time. GET A HEATER CONTROLLER!!!!
