I have the 48" tall Chicken Net and I love it.  I don't electrify it and it keeps my adult ducks (wings are clipped) and chickens in 
most of the time.  The downside to this cheaper netting is the rather floppy posts and spacing between the posts which results in sagging.  It needs to be supported with extra posts, especially at the corners, and staked to the ground to prevent the birds from escaping underneath (it comes with stakes).  I don't move it as often as you plan to so I have T-posts at each corner and fiber rods between each post.
Since you want to move it often you may want to go for one with posts that are closer together so it is faster to set up and take down.
I recommend the fences with posts that have a single spike.  I have another brand of electric netting with double spiked posts and I do not like them at all.  The spikes bend and break in rocky soil and end up misaligned which makes them difficult to replace into the ground.
