I see they are 600 bucks! For 500 I will do a crude lifesize real mount that would blow his out of the water, mine will be heavier though.. Also can't do them until I get some lifesize skins next fall. I'm making myself one for sure.
One of my buddies that is a taxidermist took a carrylite decoy and attached a big doe deer hide to it. Looks sweet and he has killed many deer over it.
I am not tight with money but $600 for a decoy is insane. I know several guys that have attached a hide to a decoy with great success.
Cooter, check out ebay, sometimes you can grab a hide for cheap off of there. Also, try a few of the local taxi's, sometimes they are willing to part with a hide, might cost you a little though.

The price is high but great quality. I have $720 in turkey decoys. Soon to be $840. I love quality and dont mind paying for it. cooter, check the taxidermy forums. They have full body hides for sale all the time.
