I bought the MJ Natural Wavemaker System from Foster/Smith a while back for my 55gal. Three powerheads (you choose the size) and a wavemaker/power strip to control them. I am quite happy with it so far, though I hear it can reduce the life of the powerhead by turning them on and off. A good deal IMO and it keeps the water moving!
Just noticed that you have a 110 tall. I am setting up the same one right now! Check out the pics of the spray bar I made for it. I'll update my build thread on it later today (I hope!) and hopefully that will give you a better idea of what I'm doing.
