I would think it's not worth it. It takes me 10 minutes to fill 5 tubes (i.e. 500 primers). That's the entire time from the moment I step up to the loading bench to the time I've got everything put away and I'm washing my hands. My approach was to buy a total of five tubes with the machine, then charge 5 tubes at a time. It's really easy and convenient. They've got a good system.
