Wavemakers, waveboxes, powerheads? UGH, how do you make a choice?

Does anyone run a Tunze Wavebox 6212??? I have looked at every ad, every thread I can and am more undecided than I was...I don't know what to add to our 150g for more and random flow....
I had thought of a couple of 6100 Tunze with controller, then I had thought about the Tunze wavebox, but then I had some other ideas.....my tank is going to be SPS and zoos, with the occasional LPS, I need more flow and would like input on what YOU do for more flow on your tanks....THANKS so much in advance for your input!
