I agree. I have the Maxspect Razor from Coralvue. I love it but but you can see that the quality of the grey housing is not top notch but its only $500. I feel I got my moneys worth with it though. Actually it was $450 when it first came out. I agree the Ecotech powerheads are overpriced but most people agree that they are the best. I have never used Tunze. I don't like the idea of buying a separate controller.
