I have 2 Doz "Hot Buy" mallards in my spread, and I'm very pleased with them. As for weights, I just bought the cheapest strap weights I could find, and a 500' spool of GHG chord. I like using strap weights because you can easily pinch them around your keel so you don't chip your paint, and if you ever get into the wind or a light current you can bend them into a U shape to help them hold the bottom. I don't know how much money you are willing to spend, but you may want to go this rout to get started.

It has everything you need for rigging, and a bag to haul your gear to and from. The quivering duck buts don’t' do a lot when it is dead calm, but if there is a slight breeze the ripples add a little extra to your spread.
