My advice,

Avoid the foam ones. They spin and move too much in the wind, paint peels off faster, hardly ever hold their shape, and have that silly ridge running around them where they came out of the mold. Frankly I don't think they look very realistic. As you can tell, I don't like them and threw all the ones I had away. Just a personal preference based on a good bit of past experience.

When I use decoys (typically only when hunting with my 12 year-old son or in the rain) now I only use the plastic collapsible ones and I think She-mobile is the best. You can sit it down on the ground in a submissive position with a strutter or stake it like any other decoy. The paint is durable and the decoy always holds its shape. All you have to do is hit it with a warm hair dryer or set it out in the sunshine and it pops right back. The way the stake is designed you screw the wing nuts down and the decoy doesn't move excessively in the wind. A well designed, well-thought-out decoy that is worth the money in my opinion.

One more suggestion: Always transport and store the decoy with an old dark sock over the head (I use the green wool army socks). The head is the first place that the decoy will start to loose paint and the sock will protect it from the inevitable bumping and banging around.
