i have had jbj, oceanic, current usa, and aqua logic. they all have some short comings. oceanic and aqua logic are more quiet. i think the aqua logic is a bit built better than the oceanic. the inline ones are better than the drop in's.....drop in creates cold spot in your sump.
hp depends on how many degrees you need to pull down. for a 220 gal.+ sump, i would go with a 1/3 hp.(a 1/2 if you plan to add volume like a frag tank, species tank, etc.), a separate controller like a ranco or use your controller...that's better than any built-in controller/thermostat and an eheim pump....more efficient than the mags and less heat.
i never own a trade wind but that's the one recommended by a buddy of mine who's a refrigeration guy and a reefer.
