I have printed at least 4 rolls of the eSun PETG & a couple of the eSun PLA rolls & like the quality of both. I printed all the plastic parts form my Mostly Printed CNC machine with the PETG & it is quite solid. You can also order the eSun from amazon or http://www.intservo.com/ for a little less than Makerfarm and not worry about shipping costs. My plastic Y-build plate that I replaced my 10" wooden build plate was printed in blue PETG & has probably a thousand hours of print time on it. http://www.thingiverse.com/thing:824227
