Heres a quick sum-up of several commonly avaliable powerheads
Tunzes'- really good, solid broad flow, can hook up to wavemakers, etc, popular in europe, many swear to them, can be found online
SEIO's- good, solid powerheads, produce a large, broader flow "poor-man's tunze", still not really that cheap though.
Hydor Koralias- good at being contorted to face different directions, decent broad flow
AquaClears, penguins, maxijets, etc produce a thin stream of flow that tends to lose alot of current as distance increases, not too expensive
