If you have time, it doesn't take much effort to make them out of foam, and you can make thm a little more accurate than Mallard bodies. I just finished up 8 Oldsquaws that I made out of Cedar. I used zip ties for the tails.
I've had great luck with them decoying, but they die hard, and bleed all over the boat.
