quietest return pump?

reef supply canada dot com has those available. Nick is good to deal with as well.

I'm looking at power consumption a for pumps. How can some pumps get 200gph with 90 watts while others use 200 watts for 2000gph

I believe the biggest difference is between A/C versus D/C control. The Red Dragons, etc...have always been good power savers versus the output.

So the dc pumps are more efficient?

Pump efficiency is based on many things like the type of motor, bearings, impellers and overall design. Red dragons use high quality motors, special ceramic bearings and are designed for the specific purpose. Many other pumps are just modified utility pumps or from other applications where efficiency is not of high concern. The RDs are also quiet as a result of being balanced better so they produce very little vibration which also adds to efficiency. I use a RD pump and you can hardly tell it's on even when used externally. I don't have any complaints but I think before I would invest in another one I would consider the much cheaper water blasters which seem to have similar design and specs.

Thanks! I plan on getting one soon.

Yes, DC pumps very efficient. The DC5000 I believe uses 40 W at 1320 GPH.
