It's worth it. I recently bought a Sicce Wave Surfer and it's good. Definitely made me a believer in controlling flow. Another one I would look into is a Tunze 7092 controller. I went with sicce because I already had 2 sicce powerheads and love them despite their somewhat ugly looks.
As far as Hydor, I am a little disappointed with their powerheads having used 2 of them personally. But their wavemaker may be good.
