there are so many it is hard to say.
the push pull is the easiest to use.the box is about the next.I make scratch boxes and they are easy to use.

then you have the diaphrams,once you learn to usse them they are great when the bird gets close.

good luck on your chose.<img src=icon_smile_cool.gif border=0 align=middle>
