I recently purchased a Champion WheelyBird battery powered trap from Amazon.com and am very impressed with it for the size and cost. It's not very large, is well built and is made to be mobile. The only thing I would have liked is slightly larger tires to make it easier to move around in the woods and field.

Amazon was about $30-50 cheaper then everywhere else I looked. For about $250 it sure beats having to use a manual trap by hand and it throws a nice target. Unlike most manual traps you can use the WheelyBird alone if you want to as it comes with a foot pedal release. My next move will be to pick up the wireless remote for it. It is also adjustable so you can have a variety of target presentations and speeds.
