One difference is that you can get the EVO with a handle for manual processing. Additionally, my understanding is that, the larger bullet, and case feeders, primer collator, digital powder measure, and auto drive are options for the EVO and are part of the revolution. Finally, if you get all the optional equipment for the EVO to basically turn it into a Revolution there still is one difference in how the auto drive is implemented between the two machines. The EVO is belt driven and the Revolution is direct drive. My information is from talking to friends that have them and not from the company so take what I say with a grain of salt.
