Cool you'll love it, no doubt.
Amazon has the cheap $10 magnets that you pull a handle and it drops all the pins
Also, which ever size brass you put into the tumbler - try to keep it around the Frankford 30 something pound rating total. If you over-load the tumbler your brass won't be so shiny
I can still do 2-3 X as much in this as my Lyman Turbo-Pron and 5X my ultrasonic.
PS - if you need to reload the cases within 30/45 minutes after pulling out of the tumbler, rather than air drying you can grab a $35 Food Dehydrator from Amazon that will dry your brass quick.
