You can make them cheap if you have the time.
go to a sign shop and buy sheets of black sign plastic, the stuff that has holes in it that you poke the metal stake into to push into the ground.
Make a template that you will use to cut out the silouettes. I used a G&H shell and just traced around it. Cut that template out of the sign board or use cardboard if you want. You can also use a windduk as a template, but the G&H's are bigger.
Take your template and trace around it on the sign sheet. Make sure you have the holes pointing vertical so the stakes will work. Cut them out using a jig saw with a fine blade.
Paint the whole thing flat black to take out the shine. This will also be the black on the tail. Make a template for the grey part of the duck and spray that. Then make one for the other colors. Use flat white in a can to paint on the neck stripe and the tail stripe.
I went to a local paint shop and had them custom make the colors right off a decoy with flat paint. Was cheap and goes a long way. Takes a little longer with brushed paint, but it looks creat.
You can make about 40 dekes out of one sheet of 4 by 8 plastic.
Go to a store that sells steel rod (look in the yellow pages) and get the kind that is just smaller than the holes in your plaxtic. Stick them through the deke and bend it on the top. Below the bottom of the deke electical tape around the stake to keep the deke from dropping to the ground. This also allows the dekes to move freely on the stake.
I have about 100 of these that I mix in with my 200 G&H shells and about 400 Falmbeaus with the keels cut off. The siloouettes move with the slightest wind. If they get too crazy in high winds, just push them further into the ground.
