Ultimately I prefer Tunze Streams over just about any other "powerhead", and will be using a couple of them off of a multicontroller in a 75g sps system I am getting ready to setup. Having said that, they are not the cheapest alternative out there. If you are wanting something with similar, but not exact flow patterns as the Streams, take a look at the Rio Seio pumps. Down side to them is that you can not pulse them on and off without risk of premature failure. For something that would vary some for random water flow, and not break the budget, look at using 4 x MJ1200s with a wavemaker on them. HTH
