There's no denying that the build will take you a while - especially if you have a family and/or demanding job. There also isn't a great MMU option, which is a good reason to look elsewhere given your interest. I am vaguely interested in a MMU, but more so from a dual extruder perspective so I can print a pair like ASA and PETG for removable supports. Their printing temperature needs aren't compatible enough for a single extruder to make much sense.
