Thanks for the replies! I ordered the Duet 2 WiFi with 5" screen. Not the clone. Hopefully I can squeeze it into the stock screen location with some trimming of the hole for the screen. I was thinking about the Duet 3 but it seems like overkill. Even if its $50 more. I think the CPU runs at 800 MHZ and has 6 drivers. That board is meant for bigger machines. Probably fabrication machines. Also no WiFi. Ethernet only.
