Somewhere on here we have some of the early drawings of the Icecap powerhead (I can't locate them right off).

But I agree with the majority, Tunze are top notch, but the premium price tag they draw sends people scattering trying to hide the credit card reciepts. The Seio pumps are a good alternative at a fraction of the cost if you are not looking for all the bells and whistles of a controller, we have a pair of M1500's running now and they perform very well. Though I think another pair might be in order just for good measure.
