If I may join in the conversation, I found that the Flashforge Finder 3D printer is Affordable and is very reliable I find. (look at other reviews for confirmation ;3) Also VERY important thing to note: ONLY PRINTS IN PLA.(PLA is cheaper than ABS but weaker, it also seems to be easier to print in and less likely to fail)
