If you want to buy a new printer, the best value for money at this moment i would say is the Creality CR-10
(i want to upgrade to it :) )
Youtubers that make 3d printing video's are extreem positive about this machine and have made very nice review video's about it, and there is a big active community behind it.
It sells for around 400 dollar and can print 300 x 300 x 400mm
