$20, reviews are good. My 10 year old got a Laserlyte pistol trainer with the knock down cans for Christmas from his cousin David at 7 Elements, so I ordered one for instore pickup at the Sam's on Meridian. Appears all the metro stores except Moore has them. Reviews seem good, but it should do fine for what I need it to do.
