Did you ever settle on a 3D printer? Have had lots on my plate but one thing I bought a wee over a year ago Creality CR10S4. 400mm x3 build area. Yes there is a learning curve, it must be certified mechanically when assembled and then dialed in further. Creality will have their new CR-X dual extruder availqble shortly.
