Original. There's been a wealth of information and spare parts to fix them over the past two decades. No doubt they will be easily maintained for a couple decades more. Sure MMR might be more reliable, but it's not more maintainable. If I'm spending $8k on a stupid toy, I need to know I can fix it easily myself when it inevitably breaks down the line. As a normal collector and not one of the smart electronics repair guys, all the tiny surface mount chips and LEDs on the giant remake PCB scare me.
