So I have a Blaze Trap in the Nether and I am selling it for 25k rupees, which you will easily make back if you use the grinder and sell enchanted pickaxes. NOTE: I have my own spawner nearby, if you grief ANY of it, I will hunt. You. Down. Thanks! DISCLAIMER: http://empireminecraft.com/threads/guide-selling-mob-spawner-locations.9738/
