What duck to buy?

[runningbeat]

I am going to an exotic bird auction in Innisfail Alberta. Its suppose to be one of the best with lots of varities. I have always had Pekins and Roues. I have a medium size pen for them inside a building and fenced area. I let my ducks out everyday. We have a creek close by that only runs for about 1 1/2 months after that they use a small childs pool.
I would like to try a different breed. Something not loud, that does not need a pond and is not aggressive towards people. Beauty would be a plus.
What breed would you suggest? thanks
