12×18 is a MASSIVE press. I learned on an 8×12, and was considering buying a 10×15, but found it too big. Please be realistic about whether or not you’ll be comfortable printing on it, and keep in mind that you’ve got several hundred dollars to move it, and several hundred (up to a thousand) to get it print ready. From the photo it looks like every bit of it has rust – this will be months of full time work to get it ready to print. My advice would be to hold out for a press that’s smaller and in better shape.
