3d printers

Anyone have one? i am just starting to get into it. i already use cad/cam software and run g-code but i am curious what anybody might have experienced / experience with theirs. I just pre ordered the prusa i3 mk3 kit with the multi extruder addon but looks like i will not be receiving it till February. i have been watching 3d printing nerd and maker's muse videos online to get acquainted with 3d printing but always like as much info as possible.
