Hoppes has a spring loaded one with a pull string release, you stake it into the ground for the easiest setup, or it can be mounted. I attach the pull cord to my boot and just slide my foot back to release the clays.
Where you place the clay on the arm allows you to throw extreme right ,extreme left and anywhere in between. The arm can be raised and lowered also. A spring tension knob allows soft throws for beginners and when you tighten it up it will throw them way out there, hard and fast. It will throw doubles, but they can go anywhere.
Mine was only $29.99 and I believe they still can be had at that price. The best method is to have one guy throw and change things up, so the shooter can not anticipate where they will go. I highly recommend it.
